Below the tourist town of Jackson, the river turns west and flows through Snake River Canyon, cutting through the Snake River Range and into eastern Idaho. These boats were the Harvest Queen, John Gates, Spokane, Annie Faxon, Mountain Queen, R.R.

At its height, there were at least 27 Nez Perce settlements along the Clearwater River and 11 more on the Snake between the mouth of the Clearwater and Imnaha Rivers. They also referred to the Shoshone Indians as the "Snake Indians", which became the present-day name of the river. [8], The river's flow is also measured at several other points in its course. Later American explorers, some of whom were originally part of the Lewis and Clark expedition, journeyed into the Snake River watershed and records show a variety of names have been associated with the river. This method raises controversy to the effectiveness and costs, since this method is extremely expensive, almost costing $15 million. [53] Grain, mostly wheat, is the main product shipped from the Snake, and nearly all of it is exported internationally from the lower Columbia River ports. [56] In the eastern Snake River Plain there is some evidence of Clovis, Folsom, and Plano cultures dating back over 10,000 years ago. In higher elevations, conifer forests, of which ponderosa pine is most common, dominate the landscape. At one point, sign language used by the Shoshones representing weaving baskets was misinterpreted to represent a snake, giving the Snake River its name.[10]. However, aside from restoring salmon runs, dam removal proponents argue that the power is replaceable, that the grain transportation system could be replaced by railroads, and that only one of the four reservoirs supplies irrigation water.

Religious groups, witchcraft trials, ivy league universities, and assembly lines are a few things that have drawn the colorful history of the United States. From there it turns south, flowing through downtown Idaho Falls, then past the Fort Hall Indian Reservation and into American Falls Reservoir, where it is joined by the Portneuf River. From there the Snake resumes its journey west, entering the Snake River Canyon of Idaho. As for Hart Hunney, Leigh said that Hunney operated in the vicinity of Heart Lake between 1840 and 1850 and died in a fight with Crow Indians in 1852. [95], It is found that over 60% of fisherman are in favor of dam removal on the Snake River. However, they were enemies to the Shoshone and the other upstream Snake River tribes. Especially in the headwaters and the other mountainous areas strewn throughout the watershed, the gray wolf, grizzly bear, wolverine, mountain lion and Canada lynx are common. When the Teton Range uplifted about 9 million years ago along a detachment fault running north–south through the central Rockies,[21] the river maintained its original course and cut through the southern end of the mountains, forming the Snake River Canyon of Wyoming. Runoff from several feedlots was dumped into the river until laws made the practice illegal. [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. [41], Mountain ranges in the Snake watershed include the Teton Range, Bitterroot Range, Clearwater Mountains, Seven Devils Mountains, and the extreme northwestern end of the Wind River Range. It was just opened, since an avalanche of dirt had closed the road. Frank Bradley of the 1872 survey gave the name "Lewis Fork" (of the Snake) to the present-day Lewis River. [50] The discharge further increases to 19,530 cu ft/s (553 m3/s) at Hells Canyon Dam on the border of Idaho and Oregon. Salmon swimming upstream in this river are faced with predators and dams. The explorer Wilson Price Hunt of the Astor Expedition named the river as Mad River. American Falls Dam, upstream of Minidoka, was completed in 1927 and replaced in 1978. Swinging northwest near the mouth of Greys River, it enters Idaho through the Palisades Reservoir. In the summer of 2013, more than 13,000 sockeye salmon returned to the spawning grounds. About 14,500 years ago, pluvial Lake Bonneville in the Great Salt Lake area, formed in the last glacial period, spilled catastrophically down the Portneuf River into the Snake in an event known as the Bonneville Flood. Evidently, Capt. (Prior to the removal of Lewiston Dam on the main Clearwater and Grangeville Dam on the South Fork Clearwater, the Clearwater was completely unusable by migrating salmon. [64][65] The name "Lewis Fork", however, did not last.[63]. Historian Daniel S. Meatte divides the prehistory of the western Snake River Basin into three main phases or "adaptive systems".

[98][99], The Upper Snake freshwater ecoregion includes most of southeastern Idaho and extends into small portions of Wyoming, Utah, and Nevada, including major freshwater habitats such as Jackson Lake. The Snake River Canyon (also known as the Grand Canyon) is formed by the Snake River in western Wyoming, United States, south of Jackson Hole. Eventually, two large Native American groups controlled most of the Snake River: the Nez Perce, whose territory stretched from the southeastern Columbia Plateau into northern Oregon and western Idaho, and the Shoshone, who occupied the Snake River Plain both above and below Shoshone Falls. The Hells Canyon Project was built and maintained by Idaho Power Company starting in the 1940s, and was the second of the three major water projects on the river. Heart Lake Lying in the Snake River watershed west of Lewis Lake and south of Yellowstone Lake, Heart Lake was named sometime before 1871 for Hart Hunney, an early hunter. About 274 bird species, some endangered or threatened, use the Snake River watershed, including bald eagle, peregrine falcon, whooping crane, greater sage-grouse, and yellow-billed cuckoo.

The Snake River flowing through Hagerman Fossil Beds National Monument, southern Idaho. [38] Most of the Snake River basin consists of wide, arid plains and rolling hills, bordered by high mountains. [86] The first dam constructed for the project was Minidoka Dam in 1904; its power plant began operating in 1909, producing 7 MW of electricity. Many of the rivers that flow into the Snake River Plain from the north sink into the Snake River Aquifer, but still contribute their water to the river. In 1926, John G.
