The Snake winds its way through Idaho Falls and provides the water for the argriculturally rich Snake River Plains. The Snake River Plain is dominated by grand lava flows. The northern reaches of the plains are dry desolate land dotted with volcanic cones. The southern reaches are extremely productive agricultural lands.
The Snake River has several major falls as it winds its way through the lava fields at Idaho Falls, American Falls, and most notably Twin Falls where the river drops into a deep gorge. The Oregon Trail follows the Snake River through much of Idaho.
The Snake River enters Oregon a little south of I84 and Ontario. It then turns north and defines the Oregon/Idaho border. North of Farewell Bend, the river drops into Hells Canyon, which is one of the deepest gorges in North America. This section of the river is one of the rafting destinations in the US. The river continues north, and defines the Idaho/Washington border.
At Lewiston, the Snake River joins the Clearwater and flows westward into Washington. The river flows into the Columbia at Kennewick, Washington.
