Beginning at Cheney, Washington , the trail runs to the confluence of the Snake and Columbia rivers at Pasco , passing through five counties in

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

Idaho

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

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
690-425: 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 9,300-year-old skeletal remains of Kennewick Man , one of

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

3680-595: 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

4830-556: 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
