67-662: Mojave National Preserve is a United States National Preserve located in the Mojave Desert of San Bernardino County, California , US, between Interstate 15 and Interstate 40 . The preserve was established October 31, 1994, with the enactment of the California Desert Protection Act by the United States Congress , which also established Joshua Tree National Park and Death Valley National Park as National Parks . Previously, some lands contained within

134-682: A lava plateau. In the later Pliocene and into the Pleistocene , these basaltic flows were covered by successive thick and fluid flows of andesite lava, which geologists call the Juniper lavas and the Twin Lakes lavas. The Twin Lakes lava is black, porphyritic and has abundant xenocrysts of quartz (see Cinder Cone ). Another group of andesite lava flows called the Flatiron, erupted during this time and covered

201-401: A stratovolcano in the southwestern corner of the park during the Pleistocene . It was made of roughly alternating layers of andesitic lavas and tephra ( volcanic ash , breccia , and pumice ) with increasing amounts of tephra with elevation. At its height, Tehama was probably about 11,000 ft (3,400 m) high. Approximately 350,000 years ago its cone collapsed into itself and formed

268-572: A wilderness area within Mojave National Preserve of approximately 695,200 acres (281,300 ha). The National Park Service manages the wilderness in accordance with the Wilderness Act , the CDPA, and other laws that protect cultural and historic sites in the wilderness. Upon the preserve's establishment, Mary Martin was designated as its superintendent, she served from 1994 to 2005, when she

335-637: A Mediterranean-influenced warm-summer Humid continental climate ( Dsb ). According to the United States Department of Agriculture , the Plant Hardiness zone at Kohm Yah-mah-nee Visitor Center at 6,736 ft (2,053 m) elevation is 6b with an average annual extreme minimum temperature of −0.2 °F (−17.9 °C). Since the entire park is located at medium to high elevations , the park generally has cool-cold winters and warm summers below 7,500 ft (2,286 m). Above this elevation,

402-549: A National Park on August 9, 1916. The 29 mi (47 km) Main Park Road was constructed between 1925 and 1931, just 10 years after Lassen Peak erupted. Near Lassen Peak the road reaches 8,512 ft (2,594 m), making it the highest road in the Cascade Mountains. It is not unusual for 40 ft (12 m) of snow to accumulate on the road near Lake Helen and for patches of snow to last into July. In October 1972,

469-412: A community less diverse than the mixed-conifer forest. Common plants include satin lupine , woolly mule's-ears and pinemat manzanita . Subalpine areas include the upper limit for the growth of standing trees. From 8,000 feet to treeline, plants are fewer in overall number with exposed patches of bare ground providing a harsh environment. Rock spirea , lupin , Indian paintbrush , and penstemon are

536-420: A few of the rugged members of this community. Trees in this community include whitebark pine and mountain hemlock. Species that are typically found in these forested areas are black bear , red fox , mule deer , marten , cougar , brown creeper , a variety of chipmunk species, raccoon , mountain chickadee , pika , a variety of squirrel species, white-headed woodpecker , coyote , bobcat , weasel ,

603-702: A pack consisting of a breeding pair and at least one offspring was reported within Lassen Volcanic Park by the California Department of Fish and Wildlife. The pack was likely formed by dispersing members from the Lassen Pack, which lives within Lassen County outside of the national park, and marks the first modern presence of wolves within the park itself. In the Cenozoic , uplifting and westward tilting of

670-460: A portion of the park was designated as Lassen Volcanic Wilderness by the US Congress (Public Law 92-511). The National Park Service seeks to manage the wilderness in keeping with the Wilderness Act of 1964, with minimal developed facilities, signage, and trails. The management plan of 2003 adds that, "The wilderness experience offers a moderate to high degree of challenge and adventure." In 1974,

737-486: A red fir, Abies magnifica ( 7 ) potential vegetation type with a California Conifer Forest ( 2 ) potential vegetation form. Lying at the northern end of the Sierra Nevada forests ecoregion, Lassen Volcanic National Park preserves a landscape nearly as it existed before Euro-American settlement: its 27,130 acres (10,980 ha) of old growth include all of its major forest types. At elevations below 6,500 feet

804-451: A series of minor to major eruptions occurred on Lassen. Because of the eruptive activity and the area's stark volcanic beauty, Lassen Peak, Cinder Cone, and the area surrounding were established as a National Park on August 9, 1916. The Atsugewi have inhabited the area since long before white settlers first saw Lassen. They knew that the peak was full of fire and water and thought it would one day blow itself apart. European immigrants in

871-410: A series of minor to major eruptions occurred on Lassen. These events created a new crater, and released lava and a great deal of ash . Fortunately, because of warnings, no one was killed, but several houses along area creeks were destroyed. Because of the eruptive activity, which continued through 1917, and the area's stark volcanic beauty, Lassen Peak, Cinder Cone and the area surrounding were declared

938-509: A significant increase in volcanic activity be detected, the USGS will immediately deploy scientists and specially designed portable monitoring instruments to evaluate the threat. In addition, the National Park Service (NPS) has developed an emergency response plan that would be activated to protect the public in the event of an impending eruption. A downhill skiing site operating in the area

1005-561: A terrible height" and "burning lava running down the sides" in the area of Cinder Cone. As late as 1859, a witness reported seeing fire in the sky from a distance, attributing it to an eruption. Early geologists and volcanologists who studied the Cinder Cone concluded the last eruption occurred between 1675 and 1700. After the 1980 eruption of Mount St. Helens , the United States Geological Survey (USGS) began reassessing

1072-419: A two-mile (3.2 km) wide caldera after it emptied its throat and partially did the same to its magma chamber in a series of eruptions. One of these eruptions occurred where Lassen Peak now stands, and consisted of fluid, black, glassy dacite , which formed a layer 1,500 ft (460 m) thick (outcroppings of which can be seen as columnar rock at Lassen's base). During glacial periods (ice ages) of

1139-453: A variety of mouse species, long-toed salamander , skunk , and a wide variety of bat species. Areas such as Reflection Lake attract waterfowl, including Canada geese, great blue heron, snowy egret, and kingfisher. Lassen Volcanic Park is home to the Sierra Nevada red fox in particular, one of the rarest mammals in California. 20 individuals have been identified in the park, making it

1206-534: Is a national park of the United States in northeastern California . The dominant feature of the park is Lassen Peak , the largest plug dome volcano in the world and the southernmost volcano in the Cascade Range . Lassen Volcanic National Park is one of the few areas in the world where all four types of volcanoes can be found: plug dome , shield , cinder cone , and stratovolcano . The source of heat for

1273-558: Is a cinder cone volcano and associated lava flow field that last erupted about 1650. It created a series of basaltic andesite to andesite lava flows known as the Fantastic Lava Beds. There are four shield volcanoes in the park; Mount Harkness (southwest corner of the park), Red Mountain (at south-central boundary), Prospect Peak (in northeast corner), and Raker Peak (north of Lassen Peak). All of these volcanoes are 7,000–8,400 feet (2,133–2,560 m) above sea level and each

1340-402: Is accessible via State Routes 89 and 44 . SR 89 passes north–south through the park, beginning at SR 36 to the south and ending at SR 44 to the north. SR 89 passes immediately adjacent to the base of Lassen Peak. There are five vehicle entrances to the park: the north and south entrances on SR 89; and unpaved roads entering at Drakesbad and Juniper Lake in the south, and at Butte Lake in

1407-464: Is also the southernmost non-extinct volcano of the Cascade Range (specifically, the Shasta Cascade part of the range). The 10,457 ft (3,187 m) tall volcano sits on the north-east flank of the remains of Mount Tehama , a stratovolcano that was a thousand feet (305 m) higher than Lassen and 11 to 15 mi (18 to 24 km) wide at its base. After emptying its throat and partially doing

1474-619: Is for a higher elevation area in the preserve. See also Climate of the Mojave Desert . United States National Preserve There are 21 protected areas of the United States designated as national preserves . They were established by an act of Congress to protect areas that have resources often associated with national parks but where certain natural resource -extractive activities such as hunting and mining may be permitted, provided their natural values are preserved. The activities permitted in each national preserve vary depending on

1541-806: Is home to ten of them, including the largest, Noatak National Preserve . Their total area is 24,651,566 acres (99,761 km ), 86% of which is in Alaska. All national preserves except Tallgrass Prairie permit hunting in accordance with local regulations. A national preserve differs from a national reserve as management of reserves can be delegated to the state in which they are located. The first national preserves were Big Thicket National Preserve in Texas and Big Cypress National Preserve in Florida, both established in 1974. The Big Cypress Swamp, adjacent to Everglades National Park and originally intended to be included in it,

1608-538: Is just north of Lassen Peak. Phreatic (steam explosion) eruptions, dacite and andesite lava flows and cinder cone formation have persisted into modern times. There are active hot springs and mud pots in the Lassen area. Some of these springs are the site of occurrence of certain extremophile micro-organisms, that are capable of surviving in extremely hot environments. [REDACTED]  This article incorporates public domain material from websites or documents of

1675-470: Is no administrative difference. The remaining ten are stand-alone units. Jean Lafitte National Historical Park and Preserve has a preserve site that is managed like one, but is not distinguished as a national preserve in the authorizing legislation and is not listed here. The Salt River Bay National Historical Park and Ecological Preserve is a unique designation that is dissimilar to national preserves. National preserves are located in eleven states; Alaska

1742-412: Is often found in the mountains during the winter. The preserve faces challenges based on its lack of funding, as of 2018 the preserve had a deferred maintenance of $ 118,036,341. This lack of funding has primarily lead to infrastructure disrepair which, in combination with the reckless driving prevalent among visitors, has caused a significant threat to the endangered Desert Tortoise population within

1809-465: Is studded with small lakes, but it boasts few streams. Warner Valley, marking the southern edge of the Lassen Plateau, features hot spring areas (Boiling Springs Lake, Devils Kitchen, and Terminal Geyser). This forested, steep valley also has large meadows that have wildflowers in spring. Lassen Peak is made of dacite , an igneous rock , and is one of the world's largest plug dome volcanoes. It

1876-433: Is topped by a cinder cone volcano. During ice ages , glaciers have modified and helped to erode the older volcanoes in the park. The center of snow accumulation and therefore ice radiation was Lassen Peak, Red Mountain, and Raker Peak. These volcanoes thus show more glacial scarring than other volcanoes in the park. Despite not having any glaciers currently, Lassen Peak does have 14 permanent snowfields. The park

1943-730: The Kelso Dunes , the Marl Mountains and the Cima Dome , as well as volcanic formations such as Hole-in-the-Wall and the Cinder Cone Lava Beds . The preserve surrounds Providence Mountains State Recreation Area and Mitchell Caverns Natural Preserve , which are both managed by the California Department of Parks and Recreation . Impressive Joshua tree forests are found in parts of the preserve. The forest covering Cima Dome and

2010-494: The National Park Service took the advice of the USGS and closed the visitor center and accommodations at Manzanita Lake . The Survey stated that these buildings would be in the way of a rockslide from Chaos Crags if an earthquake or eruption occurred in the area. An aging seismograph station remains. However, a campground, store, and museum dedicated to Benjamin F. Loomis stands near Manzanita Lake, welcoming visitors who enter

2077-597: The Sierra Nevada along with extensive volcanism generated huge lahars (volcanic-derived mud flows) in the Pliocene which became the Tuscan Formation . This formation is not exposed anywhere in the national park but it is just below the surface in many areas. Also in the Pliocene, basaltic flows erupted from vents and fissures in the southern part of the park. These and later flows covered increasingly large areas and built

2144-651: The enabling legislation of the unit. All national preserves are managed by the National Park Service (NPS) as part of the National Park System. Eleven national preserves are co-managed with national parks or national monuments ; because hunting is forbidden in those units, preserves provide a similar level of protection from development but allow hunting and in some cases grazing . Nine of those are counted as separate official units , while New River Gorge National Park and Preserve and Oregon Caves National Monument and Preserve are each single units, though there

2211-644: The Big Cypress Watershed," though off-road vehicle use, oil extraction, hunting, and traditional use by the Miccosukee and Seminole Tribes are permitted. The Big Thicket, a large area of swamps and forests, was originally proposed to be preserved as a state park or national park, but these were opposed by timber firms who wanted to retain their logging lands. A 1967 survey by the National Park Service proposed establishing nine units representative of

2345-480: The NPS can close areas to such practices as needed. Although hunting was also allowed at most national recreation areas , this was a major change in NPS wildlife management with a fifth of its land now open to it. Five new units were established from 1988 to 2000, two of which are partnerships with local governments and landowners. The Timucuan Ecological and Historic Preserve includes sites owned by Florida State Parks ,

2412-678: The Preserve were the East Mojave National Scenic Area, under the jurisdiction of the Bureau of Land Management . At 1,542,776 acres (6,243 km), within the contiguous United States it is the third largest unit of the National Park System and the first largest National Preserve . The preserve was created within the Pacific West Region of the National Park Service and remains within that jurisdiction today. Natural features include

2479-570: The adjacent Shadow Valley is the largest and densest in the world. In August 2020, a wildfire destroyed 1.3 million Joshua Trees around Cima Dome. The ghost town of Kelso is found in the preserve, with the defunct railroad depot serving as the Visitor Center. The preserve is commonly traversed by 4 wheel drive vehicles traveling on the historic Mojave Road , part of the Old Spanish National Historic Trail . Climate in

2546-523: The area's "natural and ecological integrity in perpetuity," while permitting hunting. Following President Jimmy Carter 's 1978 establishment of 17 national monuments in Alaska, the Alaska National Interest Lands Conservation Act of 1980 redesignated four as national preserves and six as national parks or monuments paired with a preserve. These had been recommended during the legislative process as early as 1974 to resolve

2613-514: The center of Tehama's now-gone cone. Other geothermal areas in the caldera are Little Hot Springs Valley, Diamond Point (an old lava conduit), and Bumpass Hell (see Geothermal areas in Lassen Volcanic National Park ). The magma that fuels the volcanoes in the park is derived from subduction off the coast of Northern California. Cinder Cone and the Fantastic Lava Beds , located about 10 mi (16 km) northeast of Lassen Peak,

2680-586: The city of Jacksonville , and private landowners. The Tallgrass Prairie National Preserve is so designated to accommodate a public-private partnership reducing federal land ownership, and it is almost entirely owned by The Nature Conservancy . Valles Caldera National Preserve was originally established in 2000 to be operated by an independent trust, but its management was transferred to the National Park Service in 2015. The four most recently established national preserves were all expansions or redesignations of existing NPS sites. Great Sand Dunes National Monument

2747-638: The climate is harsh and cold, with cool summer temperatures. Precipitation within the park is high to very high due to a lack of a rain shadow from the Coast Ranges . The park gets more precipitation than anywhere else in the Cascades south of the Three Sisters . Snowfall at the new visitor center near the southwest entrance at 6,700 ft (2,040 m) is around 430 in (1,090 cm) despite facing east. Up around Lake Helen , at 8,200 ft (2,499 m)

2814-545: The dominant vegetation community is the mixed conifer forest. ponderosa and Jeffrey pines , sugar pine , and white fir form the forest canopy for this rich community that also includes species of manzanita , gooseberry , and Ceanothus . Common wildflowers include iris , spotted coralroot , pyrola , violets , and lupin . Above the mixed-conifer forest is the major community of the red fir forest. Between elevations of 6,500 and 8,000 feet, red fir, western white pine , mountain hemlock , and lodgepole pine dominate

2881-530: The fire entered Lassen Volcanic National Park near Juniper Lake and the entire park was closed for safety. The town of Mineral , including park headquarters, was forced to evacuate. Structure loss occurred at the Drakesbad Guest Ranch and at cabins near Juniper Lake. The Dixie Fire's advance northward was slowed by the 2012 Reading Fire footprint, but the Dixie Fire ultimately burned 73,240 acres within

2948-520: The issue of sport hunting at Lake Clark after it was used for Big Thicket and Big Cypress. While this was not the primary factor in the naming of the original national preserves, it presented a compromise to protect scenic lands and allow hunting in the National Park System without breaking precedent in parks and monuments that forbid it. The national preserves are managed in the same way as national parks, except that regulated hunting, fishing, and trapping for sport and subsistence are permitted, though

3015-551: The largest known Sierra Nevada red fox population. A repopulation of wolves in California began in late December 2011. A northwestern wolf pack originally from Oregon known as the Lassen Pack inhabits the forest surrounding this national park. Other residential California wolves are the Beckwourth and Whaleback packs. The Shasta pack, which formerly was in the forest near this park, no longer appears to be extant. In 2024,

3082-480: The lava dome pushed its way up, it shattered overlaying rock, which formed a blanket of talus around the emerging volcano. Lassen rose and reached its present height in a relatively short time, probably in as little as a few years. Lassen Peak has also been partially eroded by Ice Age glaciers, at least one of which extended as much as 7 mi (11 km) from the volcano itself. Since then, smaller dacite domes formed around Lassen. The largest of these, Chaos Crags ,

3149-554: The mid-19th century used Lassen Peak as a landmark on their trek to the fertile Sacramento Valley . One of the guides to these immigrants was a Danish blacksmith named Peter Lassen , who settled in Northern California in the 1830s. Lassen Peak was named after him. Nobles Emigrant Trail was later cut through the park area and passed Cinder Cone and the Fantastic Lava Beds . Inconsistent newspaper accounts reported by witnesses from 1850 to 1851 described seeing "fire thrown to

3216-617: The northeast. The park can also be accessed by trails leading in from the Caribou Wilderness to the east, as well as the Pacific Crest Trail , and two smaller trails leading in from Willow Lake and Little Willow Lake to the south. The segment of SR 89 through the park is typically closed during the winter due to very heavy snowfall and snowpack. According to the Köppen climate classification system, Lassen Volcanic National Park has

3283-461: The park features great lava pinnacles (huge mountains created by lava flows), jagged craters, and steaming sulfur vents. It is cut by glaciated canyons and is dotted and threaded by lakes and rushing clear streams . The eastern part of the park is a vast lava plateau more than one mile (1.6 km) above sea level. Here, small cinder cones are found (Fairfield Peak, Hat Mountain, and Crater Butte). Forested with pine and fir , this area

3350-595: The park from the northwest entrance. After the Mount St. Helens eruption, the USGS intensified its monitoring of active and potentially active volcanoes in the Cascade Range. Monitoring of the Lassen area includes periodic measurements of ground deformation and volcanic-gas emissions and continuous transmission of data from a local network of nine seismometers to USGS offices in Menlo Park, California . Should indications of

Recent tree-ring analysis has placed the date at 1666. The Lassen area was first protected by being designated as the Lassen Peak Forest Preserve. Lassen Peak and Cinder Cone were later declared as U.S. National Monuments in May 1907 by President Theodore Roosevelt . Starting in May 1914 and lasting until 1921,

3618-480: The present Wisconsinan glaciation , glaciers have modified and helped to erode the older volcanoes in the park, including the remains of Tehama. Many of these glacial features, deposits and scars, however, have been covered up by tephra and avalanches, or were destroyed by eruptions. Roughly 27,000 years ago (older data gave an age of 18,000 years), Lassen Peak started to form as a dacite lava dome quickly pushed its way through Tehama's former north-eastern flank. As

3752-438: The preserve varies greatly. Summer temperatures average 90 °F (32 °C), with highs exceeding 105 °F (41 °C). Elevations in the preserve range from 7,929 feet (2,417 m) at Clark Mountain to 880 feet (270 m) near Baker. Annual precipitation varies from 3.37 inches (86 mm) near Baker, to almost 9 inches (230 mm) in the mountains. At least 25% of precipitation comes from summer thunderstorms. Snow

3819-524: The preserve. In addition to the tortoise's threatened population, the Prairie Falcon and the Bighorn Sheep are both at a risk within the preserve. A common solution provided to help save this population is to install wildlife crossings over the main roads within the preserve, though this is currently not possible with the funding provided. The California Desert Protection Act of 1994 (CDPA) designated

3886-424: The same to its magma chamber in a series of eruptions, Tehama either collapsed into itself and formed a two-mile (3.2 km) wide caldera in the late Pleistocene or was simply eroded away with the help of acidic vapors that loosened and broke the rock, which was later carried away by glaciers. Sulphur Works is a geothermal area in between Lassen Peak and Brokeoff Mountain that is thought to mark an area near

3953-490: The snowfall is around 600–700 in (1,520–1,780 cm), making it probably the snowiest place in California. In addition, Lake Helen gets more average snow accumulation than any other recording station located near a volcano in the Cascade range, with a maximum of 178 in (450 cm). Snowbanks persist year-round. According to the A. W. Kuchler U.S. Potential natural vegetation Types, Lassen Volcanic National Park has

4020-486: The southwestern part of the park's area. The park by this time was a relatively featureless and large lava plain. Subsequently, the Eastern basalt flows erupted along the eastern boundary of what is now the park, forming low hills that were later eroded into rugged terrain. Pyroclastic eruptions then started to pile tephra into cones in the northern area of the park. Mount Tehama (also known as Brokeoff Volcano) rose as
