where does the snake river begin and end
Snake River The Snake River is a major river of the greater Pacific Northwest in the United States. At 1,078 miles (1,735 km) long, it is the largest tributary of the Columbia River, the largest North American river that empties into the Pacific Ocean.[9] Rising in western Wyoming, the river flows through the Snake River Plain of southern Idaho, then through the rugged Hells Canyon area via northeastern Oregon and the rolling Palouse Hills, to reach its mouth near the Washington Tri-Cities area, where it enters the Columbia. Its drainage basin encompasses parts of six U.S. states, and its average discharge is over 54,000 cubic feet per second (1,500 m3/s).
Snake River The Snake River is the thirteenth longest river in the United States.[9] Its watershed is the 10th largest among North American rivers, and covers almost 108,000 square miles (280,000 km2) in portions of six U.S. states: Wyoming, Idaho, Nevada, Utah, Oregon, and Washington, with the largest portion in Idaho. Most of the Snake River watershed lies between the Rocky Mountains on the east and the Columbia Plateau on the northwest. The largest tributary of the Columbia River, the Snake River watershed makes up about 41% of the entire Columbia River Basin. Its average discharge at the mouth constitutes 31% of the Columbia's flow at that point.[32][33] Above the confluence, the Snake is slightly longer than the Columbia—1,078 miles (1,735 km)[5] compared to 928 miles (1,493 km)[34]—and its drainage basin is slightly larger—4% bigger than the upstream Columbia River watershed.[6][35]
Snake River More than 11,000 years ago, prehistoric Native Americans lived along the Snake. Salmon from the Pacific Ocean spawned by the millions in the river. These fish were central to the lives of the people along the Snake below Shoshone Falls. By the time Lewis and Clark crossed the Rockies and sighted the valley of a Snake tributary, the Nez Perce and Shoshone were the most powerful peoples in the region. Some tribes adopted use of horses after contact with Europeans, which reshaped their hunting and cultures for the next few hundred years before outside settlement. Later explorers and fur trappers further changed and used the resources of the Snake River basin. At one point, a hand sign made by the Shoshones representing fish was misinterpreted to represent a snake, giving the Snake River its name.
