Middle Butte is a 6391adj=midNaNadj=mid summit located in Bingham County, Idaho, United States.

Description

Middle Butte is situated 40 miles east of Craters of the Moon National Monument and Preserve, 35 miles west of the community of Idaho Falls, and can be seen from Highway 20 midway between Idaho Falls and Arco at milepost 271. Middle Butte, so named because it is positioned between Big Southern Butte and line parent East Butte, were all landmarks for early explorers and pioneers.[4] Middle Butte is set on land belonging to the Idaho National Laboratory. Topographic relief is modest as the summit rises over 1000abbr=offNaNabbr=off above the Eastern Snake River Plain in one-half mile. This landform's toponym has been officially adopted by the United States Board on Geographic Names.[4]

Geology

Middle Butte is a cryptodome composed of basalt which formed when an underlying mass of rhyolitic magma pushed up overlying layers of basalt of the Snake River Plain, but the magma never broke the surface.[6] This manner of formation is different than that of East Butte where rhyolitic magma did break through the surface layer of basalt.

Climate

Middle Butte is located in a cold semi-arid climate zone with warm summers and cold winters (Köppen BSk).[7] Winter temperatures can drop below 0 °F with wind chill factors below −20 °F. Precipitation is relatively sparse.
