. The river then flows along the Oregon-Idaho border before entering the state of Washington and finally pouring its water into the Columbia River at the Tri-Cities. Over 11000 years ago the Snake was a vital source of life for the Native Americans specifically the Shoshones that were living along the banks of the river. It is the Columbias largest tributary an important source of irrigation water for potatoes sugar beets and other crops.

Shoshone Falls is a waterfall on the Snake River in southern Idaho approximately 48 kilometers 3 miles northeast of. Geology of the Snake River Plain Current studies suggest that the Snake River Plain resulted from the passage of the North American Plate over a stationary mantle plume or hotspot that is currently located beneath Yellowstone National Park Figure 2 or what is often referred to as the Yellowstone Caldera or Yellowstone Plateau. The upper Snake River in the study area has a braided channel pattern that migrates and shifts over time due to a stream ﬂow.

The age of the volcanic events generally progresses from oldest about 13 million years ago to the youngest episodes. Today both the fish and the tribe battle for the survival of all that sustained their way of life for so many generations. The Source Of The Snake River The Snake River begins its journey from the western side of the state of Wyoming and flows across the Snake River Plain in the southern part of Idaho.

The Snake River originates in Wyoming and arcs across southern Idaho before turning north along the Idaho-Oregon border.

As these events were then understood the McKinney Basalt flowed south toward the Snake River then west in the.

Roaring down the Idaho face of the Rockies surging with snowmelt from the Yellowstone Plateau the.

It is arc shaped with the concave side to the north. The river then enters Washington and flows west to the Columbia River. Movement of the North American plate over the Yellowstone hot spot has resulted.

To this latter point Leonhardy and Rice 1970 originally proposed the Tucannon phase to represent a break in the evolutionary continua of the southern Plateau. While they werent Snake River rafting as we are today the Snake was very important to them primarily because of the salmon from the Pacific Ocean.
