115-520: The Ochoco Mountains run 114 miles (183 km) north to south and 86 miles (138 km) east to west. The eight highest peaks in the range are: The Ochoco Mountains in central Oregon form the western end of the Blue Mountains. The Blue Mountains are not a single cohesive range, but rather a complex of ranges and inter-mountain basins and valleys that extend from southeast Washington into central Oregon, ending near Prineville . The Ochoco portion of

230-616: A temperate rainforest . Weeks may pass without a clear day. The western slopes of the Cascade Range receive some of the heaviest annual snowfall (in some places more than 200 inches or 5,100 millimeters water equivalent) in the country. In the rain shadow area east of the Cascades, the annual precipitation is only 6 inches (150 mm). Precipitation then increases again eastward toward the Rocky Mountains (about 120 miles (190 km) east of

345-426: A few days; they require warm and moist conditions to take root. The plants can also reproduce vegetatively from decapitated stumps and branches. Willows produce a modest amount of nectar from which bees can make honey , and are especially valued as a source of early pollen for bees. Various animals browse the foliage or shelter amongst the plants. Beavers use willows to build dams. The trees are used as food by

460-470: A large part of the top of the volcano. The eruption flattened the forest up to 20 km north of the volcano , killed 57 people, flooded the Columbia River and its tributaries with ash and mud, and blanketed large parts of Washington eastward and other surrounding states in ash, making day look like night. Washington is the northwesternmost state of the contiguous United States . It borders Idaho to

575-631: A large region experiences strong rain shadow effects. Semi-arid conditions occur in much of Eastern Washington with the strongest rain shadow effects at the relatively low elevations of the central Columbia Plateau —especially the region just east of the Columbia River from about the Snake River to the Okanagan Highland . Thus, instead of rain forests, much of Eastern Washington is covered with dry grassland , shrub-steppe , and dunes . The average annual temperature ranges from 51 °F (11 °C) on

690-490: A letter to the Royal Society describing his experiments with powdered bark of white willow ( Salix alba ). He had noticed the willow bark tasted bitter, like 'Peruvian Bark' ( cinchona ), which was used to treat fevers, and he speculated that the willow would have a similar effect. Over several years he tested it on as many as fifty patients and found it to be highly effective (especially when mixed with cinchona). Whether this

805-425: A low-pressure cyclone system takes over in the north Pacific Ocean. The air spiraling inward in a counter-clockwise fashion causes Washington's prevailing winds to come from the southwest, and bring cool and overcast weather and a predictably wet season . The term " Pineapple Express " is used colloquially to describe atmospheric river events, where repeated storm systems are directed by this persistent cyclone from

920-455: A preliminary assessment of the risks and opportunities presented given the possibility of a rise in global temperatures and their effects on Washington state. Rainfall in Washington varies dramatically going from east to west. The Olympic Peninsula's western side receives as much as 160 inches (4,100 mm) of precipitation annually, making it the wettest area of the 48 conterminous states and

1035-466: A proposal to use the name "State of Washington, Douglass Commonwealth", which would conflict with the current state of Washington. Residents of Washington (known as "Washingtonians") and the Pacific Northwest simply refer to the state as "Washington", and the nation's capital "Washington, D.C.", "the other Washington", or simply "D.C." The 9,300-year-old skeletal remains of Kennewick Man , one of

1150-504: A state; the creation of Idaho Territory in 1863 established the final eastern border. A Washington state constitution was drafted and ratified in 1878, but it was never officially adopted. Although never approved by the United States Congress, the 1878 constitution is an important historical document that shows the political thinking of the time; it was used extensively during the drafting of Washington state's 1889 constitution,

1265-583: A three-man commission ruling in favor of the United States in 1872. The border established by the Oregon Treaty and finalized by the arbitration in 1872 remains the boundary between Washington and British Columbia . The growing population of Oregon Territory north of the Columbia River formally requested a new territory. As a result of the Monticello Convention , held in present-day Cowlitz County ,

1380-439: A varied range of bird species. This range includes raptors, shorebirds, woodland birds, grassland birds, ducks, and others. There have also been a large number of species introduced to Washington, dating back to the early 18th century, including horses and burros. The channel catfish , lamprey , and sturgeon are among the 400 known freshwater fishes . Along with the Cascades frog, there are several forms of snakes that define

1495-513: A willow will attempt to put out leaves and flowers. In the northern hemisphere, leaf drop in autumn occurs when day length shortens to approximately ten hours and 25 minutes, which varies by latitude (as early as the first week of October for boreal species such as S. alaxensis and as late as the third week of December for willows growing in far southern areas). With the exception of Salix martiana , willows are dioecious , with male and female flowers appearing as catkins on separate plants;

1610-500: Is a hybrid of Peking willow ( Salix babylonica ) from China and white willow ( Salix alba ) from Europe. The widely planted Chinese willow Salix matsudana is now considered a synonym of S. babylonica . Numerous cultivars of Salix have been developed and named over the centuries. New selections of cultivars with superior technical and ornamental characteristics have been chosen deliberately and applied to various purposes. Many cultivars and unmodified species of Salix have gained

1725-566: Is an excellent example of this erosion . During the Eocene epoch, central Oregon volcanoes deposited layers of lava and ash up to 1,000 feet (300 m) thick over the area that is now the Ochoco Mountains. Large mudflows called lahars were also common during that period. These mudflows often covered and preserved the plants and animals, resulting in fossil beds. Today, fossils of prehistoric trees, fruits, nuts, and flowers can be found in

1840-482: Is an extremely important business throughout much of Eastern Washington, as the soil is highly productive and irrigation , aided by dams along the Columbia River, is fairly widespread. The spread of population in Eastern Washington is dominated by access to water, especially rivers. The main cities are all located alongside rivers or lakes; most of them are named after the river or lake they adjoin. Farther east,

1955-436: Is one-celled, the style two-lobed, and the ovules numerous. The scientific use of the genus name Salix originates with Carl Linnaeus in 1753. The modern concept of types did not exist at the time, so types for Linnaeus' genera had to be designated later. The type species , i.e., the species on which the genus name is based, is Salix alba , based on a conserved type. The generic name Salix comes from Latin and

2070-405: Is the only U.S. state named after a president. Confusion between the state of Washington and the city of Washington, D.C., led to renaming proposals during the statehood process for Washington in 1889, including David Dudley Field II 's suggestion to name the new state "Tacoma"; these proposals failed to garner support. Washington, D.C.'s, own statehood movement in the 21st century has included

2185-618: Is uncertain. The seeds of the Haluppu-tree were recommended in the Sumerian narrative of Gilgameš, Enkidu and the Nether World as treatment for infertility, but the "Haluppu-tree" could have been oak, poplar or willow. The ancient Egyptian Ebers Papyrus mentions willow (of uncertain species) in three remedies. One, as part of an elaborate recipe for a poultice to "make the met supple," which involved 36 other ingredients including "fruit of

2300-499: The Blue Mountains and the eastern sides of the Cascades. Mammals native to the state include the bat , black bear , bobcat , cougar , coyote , deer , elk , gray wolf , hare , moose , mountain beaver , muskrat , opossum , pocket gopher , rabbit , raccoon , river otter , skunk , and tree squirrel . Because of the wide range of geography, the state of Washington is home to several different ecoregions, which allow for

2415-435: The Blue Mountains . The state of Washington has a temperate climate. The eastern half of Washington has a semi-arid to warm-summer mediterranean climate , while the western side of Washington as well as the coastal areas of the state have a cool oceanic climate or warm-summer mediterranean climate. Major factors determining Washington's climate include the large semi-permanent low pressure and high pressure systems of

2530-532: The Canadian province of British Columbia to the north. Washington is part of a region known as the Pacific Northwest , a term which always refers to at least Washington and Oregon, and may or may not include some or all the following, depending on the user's intent: Idaho, western Montana , northern California , British Columbia, and Alaska . The high mountains of the Cascade Range run north-south, bisecting

2645-559: The Cascade Mountains westward, Western Washington has a mostly Mediterranean climate , with mild temperatures and wet winters, autumns and springs, and relatively dry summers. The Cascade Range has several volcanoes , which reach altitudes significantly higher than the rest of the mountains. From north to south, these major volcanoes are Mount Baker , Glacier Peak , Mount Rainier , Mount St. Helens , and Mount Adams . All are active volcanoes. Mount Rainier—the tallest mountain in

2760-652: The Clarno Formation . From 37 to 17 million years ago, eruptions in the western Cascade Range spread ash across eastern Oregon, forming the John Day Formation . From 17 to 14 million years ago, major volcanic eruptions covered much of the province with basalt flows, creating the Columbia River Basalt Group . Since then, continued faulting and uplift has resulted in a deeply eroded landscape. Steins Pillar, known colloquially as The Big One,

2875-675: The Columbia District . Fur trapper James Sinclair , on orders from Sir George Simpson , Governor of the Hudson's Bay Company, led some 200 settlers from the Red River Colony west in 1841 to settle on Hudson Bay Company farms near Fort Vancouver . The party crossed the Rockies into the Columbia Valley , near present-day Radium Hot Springs , British Columbia, then traveled south-west down

2990-784: The Continental Divide to the Pacific Ocean as part of the Anglo–American Convention of 1818 , which established the 49th parallel as the international boundary west from Lake of the Woods to the Rocky Mountains . Resolution of the territorial and treaty issues west to the Pacific was deferred until a later time. In 1819, Spain ceded its rights north of the 42nd parallel to the United States. Negotiations with Great Britain over

3105-528: The Kootenai River and Columbia River. Despite such efforts, Britain eventually ceded all claims to land south of the 49th parallel to the United States in the Oregon Treaty on June 15, 1846. In 1836, a group of missionaries, including Marcus Whitman , established several missions and Whitman's own settlement Waiilatpu, in what is now southeastern Washington state, near present-day Walla Walla County , in

3220-663: The Latin word salix , willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow ( Salix herbacea ) rarely exceeds 6 centimetres ( 2 + 1 ⁄ 2  in) in height, though it spreads widely across the ground. Willows all have abundant watery bark sap , which is heavily charged with salicylic acid , soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots . The roots are remarkable for their toughness, size, and tenacity to live, and roots readily sprout from aerial parts of

3335-610: The Royal Horticultural Society 's Award of Garden Merit . Most recently, Salix has become an important source for bioenergy production and for various ecosystem services . Names of hybrids and cultivars were until recently (2021) compiled by a working party of the UN FAO, the International Cultivar Registration Authority (ICRAs) for the genus Salix (willows) Archived 7 December 2018 at

3450-595: The San Juan Islands is heavily inhabited by killer , gray, and humpback whales. In Eastern Washington, the flora is vastly different. Tumbleweeds and sagebrush dominate the landscape throughout large parts of the countryside. Russian olives and other trees are common alongside riverbanks; however, apart from the riversides, large swaths of Eastern Washington have no naturally existing trees at all (though many trees have been planted and are irrigated by people, of course). A wider variety of flora can be found in both

3680-547: The State of Washington , is a state in the Pacific Northwest region of the United States. It is often referred to as Washington state to distinguish it from the national capital , both named after George Washington (the first U.S. president ). Washington borders the Pacific Ocean to the west, Oregon to the south, Idaho to the east, and shares an international border with the Canadian province of British Columbia to

3795-463: The U.S. Congress passed legislation to create Washington Territory . It was signed into law by President Millard Fillmore on March 2, 1853. The boundary of Washington Territory initially extended farther east than the present state, including what is now the Idaho Panhandle and parts of western Montana, and picked up more land to the southeast that was left behind when Oregon was admitted as

The wood was used by some Native American tribes to start fires by friction , the shoots to weave baskets , and both the branches and stems to build various items including fishing weirs . The leaves and bark of the willow have been mentioned in ancient texts from Assyria , Sumer and Egypt and in Ancient Greece

4140-447: The larvae of some species of Lepidoptera , such as the mourning cloak butterfly . Ants, such as wood ants , are common on willows inhabited by aphids , coming to collect aphid honeydew , as sometimes do wasps . Willow species are hosts to more than a hundred aphid species, belonging to Chaitophorus and other genera, forming large colonies to feed on plant juices, on the underside of leaves in particular. Corythucha elegans ,

4255-585: The "deep freeze" winters of 1883–1884, 1915–1916, 1949–1950, and 1955–1956, among others. During these events, Western Washington experienced up to 6 feet (1.8 m) of snow, sub-zero (−18 °C) temperatures, three months with snow on the ground, and lakes and rivers frozen over for weeks. Seattle's lowest officially recorded temperature is 0 °F (−18 °C) set on January 31, 1950, but low-altitude areas approximately three hours away from Seattle have recorded lows as cold as −48 °F (−44 °C). The Southern Oscillation greatly influences weather during

4370-604: The Idaho border). The Olympic mountains and Cascades compound this climatic pattern by causing orographic lift of the air masses blown inland from the Pacific Ocean, resulting in the windward side of the mountains receiving high levels of precipitation and the leeward side receiving low levels. This occurs most dramatically around the Olympic Mountains and the Cascade Range. In both cases, the windward slopes facing southwest receive high precipitation and mild, cool temperatures. While

4485-644: The Interior had a different subsistence-based culture based on hunting, food-gathering and some forms of agriculture, as well as a dependency on salmon from the Columbia and its tributaries. The area has been known to host megathrust earthquakes in the past, the last being the Cascadia earthquake of 1700 . The first recorded European landing on the Washington coast was by Spanish Captain Don Bruno de Heceta in 1775, on board

4830-741: The Ochoco Mountains are public lands administered by the United States Forest Service . The Ochoco National Forest is responsible for most of the mountain area; however, the southeastern part of the range is in the Malheur National Forest. Some land in the Ochoco area is also administered by the Bureau of Land Management . Hiking, fishing, camping, hunting, horseback riding, bird watching, and rockhounding are all popular activities. The Ochoco National Forest maintains 27 campgrounds in or near

4945-479: The Ochoco Mountains, the western juniper trees survive on as little as 8 inches (200 mm) of precipitation per year. The range's juniper woodlands cover wide areas from 3,000 to 4,000 feet (910 to 1,220 m) in elevation. Antelope bitterbrush and sagebrush are common shrubs in these areas with Idaho fescue and bluebunch wheatgrass as the main ground cover. Juniper woodlands are home to mountain bluebirds , Townsend's solitaires , and ferruginous hawks during

5060-480: The Ochoco Mountains. The largest are the Antelope Flat Reservoir , Ochoco Divide, Walton Lake, and Wildcat campgrounds. The Malheur National Forest has several campgrounds in the Ochoco Mountains as well. The largest is the campground at Delintment Lake . The unique geology of the Ochoco Mountains is such that a wide variety of rock types are located in a relatively small area. This brings rockhounds to

5175-768: The Oregon Trail, wandered north to settle in the Puget Sound area. Spanish and Russian claims to the region were ceded in the early 19th century through a series of treaties. The Spanish signed the Adams–Onís Treaty of 1819, and the Russians the Russo-American Treaty of 1824 and 1825 . The Oregon Question remained contested between the United Kingdom and the United States until the 1846 Oregon Treaty established

The highest recorded temperature in the state was 120 °F (49 °C) at Hanford on June 29, 2021. Both records were set east of the Cascades. Western Washington is known for its mild climate, considerable fog, frequent cloud cover, long-lasting drizzles in

5520-411: The Puget Sound lowlands are known for clouds and rain in the winter, the western slopes of the Cascades receive larger amounts of precipitation, often falling as snow at higher elevations. Mount Baker , near the state's northern border, is one of the snowiest places in the world. In 1999, it set the world record for snowfall in a single season—1,140 inches (95 ft; 29 m). East of the Cascades,

Mount Rainier , an active stratovolcano , is the state's highest elevation at 14,411 feet (4,392 meters), and is the most topographically prominent mountain in the contiguous U.S. Washington is a leading lumber producer, the largest producer of apples, hops, pears, blueberries, spearmint oil, and sweet cherries in the U.S., and ranks high in

5750-480: The active constituent. It was long after the invention of aspirin that the idea emerged that willow bark is an effective painkiller. It may often be based on the belief that willow actually contains aspirin. Articles asserting that the ancients used willow for this purpose have been published in academic journals such as the British Journal of Haematology . There are now many papers, books and articles repeating

5865-543: The area every summer. The Bureau of Land Management and the Ochoco National Forest both have designated areas where rockhounds can search for agate , jasper , petrified wood , petrified moss, and dendrite . These rock collection sites are for personal use only; gathering rocks for commercial purposes is prohibited. Thundereggs can be found at Whistle Springs. Even though the area has been worked by rockhounds for many years, quality thundereggs are still found at

The first wildflowers to bloom are usually grass widow, wild parsley , and shooting stars . From May through June, Wyethia , buttercups , and camas display their colors. In drier areas, bitterroot bloom with large white and pink flowers. In June and July, other flowers take over

6095-503: The border between British North America and the United States along the 49th parallel until the Strait of Georgia . Vague wording in the treaty left the ownership of the San Juan Islands in doubt; during the so-called Pig War , both nations agreed to a joint military occupation of the islands. Kaiser Wilhelm I of the German Empire was selected as an arbitrator to end the dispute, with

6210-486: The bud scale is fused into a cap-like shape, but in some species it wraps around and the edges overlap. The leaves are simple, feather-veined, and typically linear-lanceolate. Usually they are serrate, rounded at base, acute or acuminate. The leaf petioles are short, the stipules often very conspicuous, resembling tiny, round leaves, and sometimes remaining for half the summer. On some species, however, they are small, inconspicuous, and caducous (soon falling). In color,

The pistillate (female) flowers are also without calyx or corolla, and consist of a single ovary accompanied by a small, flat nectar gland and inserted on the base of a scale which is likewise borne on the rachis of a catkin. The ovary

6440-440: The catkins are produced early in the spring, often before the leaves. The staminate (male) flowers have neither calyx nor corolla ; they consist simply of stamens, varying in number from two to 10, accompanied by a nectariferous gland and inserted on the base of a scale which is itself borne on the rachis of a drooping raceme called a catkin, or ament. This scale is square, entire, and very hairy. The anthers are rose-colored in

6555-593: The causes of fevers were poorly understood, and there is no suggestion at all of any possible analgesic effect from the use of willow. The first lasting evidence that salicylate, from willow and other plant species, might have real medicinal uses came in 1876, when the Scottish physician Thomas MacLagan experimented with salicin as a treatment for acute rheumatism , with considerable success, as he reported in The Lancet . Meanwhile, German scientists tried salicylic acid in

6670-454: The center of the Ochocos is well known for its spring wild flower displays. Ponderosa pine is the dominant tree species in most parts of the Ochoco Mountains. These pines are common at elevations from 3,000 to 6,000 feet (910 to 1,830 m) above sea level. Manzanita , antelope bitterbrush , and ceanothus are common shrubs in the pine-dominated areas with Idaho fescue and Ross' sedge as

6785-653: The claim that the ancients used willow for pain relief, and numerous willow-based products can be purchased for this purpose. Modern research suggests that only the mildest analgesic effect could be derived from the use of willow extract, and even that may be due to flavonoids and polyphenols as much as salicylic acid. Some of humans' earliest manufactured items may have been made from willow. A fishing net made from willow dates back to 8300 BC. Basic crafts, such as baskets, fish traps, wattle fences and wattle and daub house walls, were woven from osiers or withies (rod-like willow shoots, often grown in pollards ). One of

6900-518: The climate becomes less arid, with annual rainfall increasing as one goes east to 21.2 inches (540 mm) in Pullman, near the Washington–Idaho border. The Okanogan Highlands and the rugged Kettle River Range and Selkirk Mountains cover much of the state's northeastern quadrant. The Palouse southeast region of Washington was grassland that has been mostly converted into farmland, and extends to

Western Washington also is home of the Olympic Mountains , far west on the Olympic Peninsula , which support dense forests of conifers and areas of temperate rainforest . These deep forests, such as the Hoh Rainforest , are among the only rainforests in the continental United States. While Western Washington does not always experience a high amount of rainfall as measured in total inches of rain per year, it does consistently have more rainy days per year than most other places in

7245-524: The country. Eastern Washington —the part of the state east of the Cascades—has a relatively dry climate, in distinct contrast to the west side. It includes large areas of semiarid steppe and a few truly arid deserts in the rain shadow of the Cascades; the Hanford reservation receives an average annual precipitation of 6 to 7 inches (150 to 180 mm). Despite the limited amount of rainfall, agriculture

It was not discovered until Charles William Barkley , captain of the Imperial Eagle , sighted it in 1787. The straits were further explored by Spanish explorers Manuel Quimper in 1790 and Francisco de Eliza in 1791, and British explorer George Vancouver in 1792. The British–Spanish Nootka Convention of 1790 ended Spanish claims of exclusivity and opened

The treatment of rheumatic fever with salicin gradually gained some acceptance in medical circles. The discovery of acetanilide , in the 1880s, gave rise to an 'acetylation' craze, where chemists experimented with adding an acetyl group to various aromatic organic compounds. Back in 1853, chemist Charles Frédéric Gerhardt treated

8050-628: The forms of Welsh coracle boat traditionally uses willow in the framework. Thin or split willow rods can be woven into wicker , which has a long history. The relatively pliable willow is less likely to split while being woven than many other woods, and can be bent around sharp corners in basketry. Willow wood is used in the manufacture of boxes , brooms , cricket bats , cradle boards , chairmans and other furniture, dolls , willow flutes , poles , sweat lodges , toys, turnery, tool handles, wood veneer , wands and whistles . In addition, tannin , fibre , paper, rope and string can be produced from

8165-538: The genus are known from the early Eocene of North America, with the earliest occurrences in Europe during the Early Oligocene . The genus Salix is made up of around 350 species of deciduous trees and shrubs . They hybridise freely, and over 160 such hybrids have been named. Examples of well-known willows include: Willows are shade tolerant and typically short-lived. They require disturbances to outcompete conifers or large deciduous species. The seeds are tiny, plentiful, carried by wind and water, and viable only for

The Roman author Aulus Cornelius Celsus only mentions willow once: the leaves, pounded and boiled in vinegar, were to be used as treatment for uterine prolapse , but it is unclear what he considered the therapeutic action to be; it is unlikely to have been pain relief, as he recommended cauterization in the following paragraph. Nicholas Culpeper , in The Complete Herbal , gives many uses for willow, including to staunch wounds, to "stay

8510-424: The heat of lust" in man or woman, and to provoke urine ("if stopped"), but he makes no mention of any supposed analgesic properties. His recommendation to use the burnt ashes of willow bark, mixed with vinegar, to "take away warts, corns, and superfluous flesh," seems to correspond with modern uses of salicylic acid . William Turner 's account, written about 1597, focuses on the ability of the leaves and bark to "stay

8625-478: The late 1990s, Daniel Moerman reported many uses of willow by Native Americans. One modern field guide claims that Native Americans across the Americas relied on the willow as a staple of their medical treatments, using the bark to treat ailments such as sore throat and tuberculosis, and further alleging that "Several references mention chewing willow bark as an analgesic for headache and other pain, apparently presaging

8740-400: The leaves show a great variety of greens, ranging from yellowish to bluish color. Willows are among the earliest woody plants to leaf out in spring and the last to drop their leaves in autumn. In the northern hemisphere, leafout may occur as early as February depending on the climate and is stimulated by air temperature. If daytime highs reach 10 °C (50 °F) for a few consecutive days,

8855-404: The main ground cover. Ponderosa pine forests are tolerant of drought and low-intensity wildfires . Birds commonly found in the pine forests of the Ochoco Mountains include the northern flicker , hairy woodpecker , red-tailed hawk , and Steller's jay .

After the end of World War II, and with the beginning of the civil rights movement ,

9085-460: The meadowlands. Quaking aspen with shrubby undergrowth attract wildlife not found in other parts of the Ochoco Mountains. Common birds include sandhill crane , Wilson's snipe , long-billed curlew , and northern harrier . Even the rare dickcissel has been sighted at Big Summit Prairie. Larger animals include mule deer, pronghorn , Belding's ground squirrel , northern pocket gopher , meadow mice, and coyotes. Also, Rocky Mountain elk move into

9200-482: The medicine sodium salicylate with acetyl chloride to produce acetylsalicylic acid for the first time. More than 40 years later in 1897, Felix Hoffmann created the same acid (in his case derived from the Spiraea plant), which was found in 1899 to have an analgesic effect. This acid was named " Aspirin " by Hoffmann's employer Bayer AG . The discovery of aspirin is therefore only indirectly connected to willow. In

9315-754: The most prominent reptiles and amphibians. Coastal bays and islands are often inhabited by plentiful amounts of shellfish and whales. There are five species of salmon that ascend the Western Washington area, from streams to spawn. Willows Willows , also called sallows and osiers , of the genus Salix , comprise around 350 species (plus numerous hybrids) of typically deciduous trees and shrubs , found primarily on moist soils in cold and temperate regions. Most species are known as willow , but some narrow-leaved shrub species are called osier , and some broader-leaved species are referred to as sallow (from Old English sealh , related to

9430-564: The next few decades failed to settle upon a compromise boundary and the Oregon boundary dispute was highly contested between Britain and the United States. Disputed joint occupancy by Britain and the U.S. lasted for several decades. With American settlers pouring into Oregon Country , Hudson's Bay Company , which had previously discouraged settlement because it conflicted with the fur trade, reversed its position in an attempt to maintain British control of

9545-459: The north Pacific Ocean, the continental air masses of North America, and the Olympic and Cascade mountains. In the spring and summer, a high-pressure anticyclone system dominates the north Pacific Ocean, causing air to spiral out in a clockwise fashion. For Washington, this means prevailing winds from the northwest bring relatively cool air and a predictably dry season . In the autumn and winter,

10005-500: The original plan for the border followed the Columbia River east until the confluence with the Snake, and then would have followed the Snake River east; this was changed to keep Walla Walla 's fertile farmland in Washington. To the west of Washington lies the Pacific Ocean. Its northern border lies mostly along the 49th parallel , and then via marine boundaries through the Strait of Georgia , Haro Strait , and Strait of Juan de Fuca , with

10120-470: The physician Hippocrates wrote about its medicinal properties in the fifth century BC. Interpreting Mesopotamian cuneiform texts is a challenge, especially when looking for something as specific as a species of plant being used to treat a recognisable condition. Some 5,000 medical prescriptions have been identified from Babylonian writings of the 7th to 3rd centuries BC, involving 1,300 drugs from 340 different plants. Whether any of these relate to willow

10235-409: The plant. The leaves are typically elongated, but they might also be round to oval, frequently with serrated edges. Most species are deciduous ; semi- evergreen willows with coriaceous leaves are rare, e.g. Salix micans and S. australior in the eastern Mediterranean . All the buds are lateral; no absolutely terminal bud is ever formed. The buds are covered by a single scale. Usually,

10695-522: The rest of the country, and for a time, it possessed a large shipbuilding industry. The region around eastern Puget Sound developed heavy industry during the period including World War I and World War II , and the Boeing company became an established icon in the area. During the Great Depression , a series of hydroelectric dams were constructed along the Columbia River as part of a project to increase

10810-566: The same time many white patients recovered, they held "medicine man" Marcus Whitman personally responsible, and executed Whitman and twelve other white settlers. This was called the Whitman massacre in 1847. This event triggered the Cayuse War between settlers and Indians. Fort Nisqually , a farm and trading post of the Hudson's Bay Company and the first European settlement in the Puget Sound area,

Britain and the United States agreed to what has since been described as "joint occupancy" of lands west of

11385-457: The state's growing Black or African American population's wages were 53% above the national average. The early diversification of Washington through the Great Migration led to successful efforts at reducing discrimination in the workplace. In 1950, Seattle's first black representative for the state's legislature was elected. At the 1970 U.S. census , the black population grew to 7.13% of

11500-485: The state's land area, mostly west of the northern Cascades. Approximately two-thirds of Washington's forested area is publicly owned, including 64 percent of federal land.

The U.S. Geological Survey considers 14,411-foot-tall (4,392 m) Mount Rainier the most dangerous volcano in the Cascade Range, due to its proximity to the Seattle metropolitan area , and most dangerous in the continental U.S. according to the Decade Volcanoes list. It is also covered with more glacial ice than any other peak in

11845-622: The territory of both the Cayuse and the Nez Perce Indian tribes. Whitman's settlement would in 1843 help the Oregon Trail , the overland emigration route to the west, get established for thousands of emigrants in the following decades.

Seattle was the primary port for trade with Alaska and

12305-903: The willow lace bug, is a bug species in the family Tingidae found on willows in North America. Rhabdophaga rosaria is a type of gall found on willows. Rust , caused by fungi of genus Melampsora , is known to damage leaves of willows, covering them with orange spots. Some Native Americans allowed wildfires to burn and set fires intentionally, allowing new stands to form. A small number of willow species were widely planted in Australia, notably as erosion -control measures along watercourses. They are now regarded as invasive weeds which occupy extensive areas across southern Australia and are considered 'Weeds of National Significance'. Many catchment management authorities are removing and replacing them with native trees. Almost all willows take root very readily from cuttings or where broken branches lie on

12420-771: The winter and warm, temperate summers. The eastern region, which does not benefit from the general moderating effect of the Pacific Ocean, occasionally experiences extreme climate. Arctic cold fronts in the winter and heat waves in the summer are not uncommon.

A theory is that the word is ultimately derived from a Celtic language , sal meaning 'near' and lis meaning 'water', alluding to their habitat. Willows are classified into subgenera though what they should be is in flux. Morphological studies generally divide the species into 3 or 5 subgenera: Salix (though some split off subgenera Longifoliae and Protitae ), Chamaetia , and Vetrix . Phylogenetic studies have suggested that Chamaetia and Vetrix be in one clade. The oldest fossils of

After them, many more settlers, migrating overland along

13225-409: Was suffering from a fever induced by a bullet wound: "The bark of the willow has, indeed, been justly considered as a succedaneum for Peruvian bark, as has also that of the horse-chestnut tree, the leaf of the holly, the snake-root, etc.", he wrote. In the story, Herbert is treated with powdered willow bark to no effect, and is saved when a supply of quinine is discovered. It is clear in the novel that
