Snake River Plain - Wikipedia
The Snake River Plain is a geologic feature located primarily within the U.S. state of Idaho. It stretches about 400 miles (640 km) westward from northwest of the state of Wyoming to the Idaho-Oregon border. The plain is a wide, flat bow-shaped depression and covers about a …

2022年12月13日 · The Snake River Plain is a prominent river drainage that cuts a broad “smile” across southern Idaho, easily recognizable from satellite imagery. The geologic history of the Eastern Snake River Plain and the Yellowstone Hotspot track are closely intertwined, but the Western Snake River Plain has a different story to tell.

Western Snake River Plain. The western Snake River Plain is 30 to 43 miles wide and trends northwest. It is a fault-bounded basin with both the land surface and the rock layers dipping towards the axis of the plain. The basin is filled by interbedded volcanic rocks and lake bed sediments of Tertiary and Quaternary age.
Yellowstone and Snake River Plain - Idaho State University
The Snake River Plain is a broad arcuate topographic depression that extends across southern Idaho. The western Snake River Plain sits in a fault-bounded graben whereas the eastern Snake River Plain (ESRP) is a large structural downwarp that formed due to the weight of mafic magmas in the subsurface as well as overlying volcanic rocks.

The Snake River Plain is a valley in the U.S. state of Idaho. It covers most of the southern part of the state and is transected by the Snake River. The Snake River Plain was formed by magma rising up below the North American Plate. As the plate moved westward, the magma melted rock under the plate.

Rising to a height of 2,300 meters (7,550 feet), the butte towers over the relatively flat Snake River Plain. It formed as lava slowly built up around a vent. A circular shadow on the brown plain in this image, Big Southern Butte is one of the largest volcanic domes in the world.
The Snake River Plain is a broad west-draining lava plateau, with mountains on its north and south sides. The Plain has the shape of a broad "V" with the top pointing north, and is divided into eastern and western parts, which meet near Hagerman, just west of Twin Falls.
Snake River Plain: a thin upper crust, low-density sediment with interbedded basalt, and massive dense basalt flows. The thinning of the upper crust, indi-cated by the refraction data, is a large positive mass anomaly and could produce most of the gravity high. Sedimentary rocks with some interbedded basalt
