Minidoka CountyMinidoka County is entirely on the Snake River Plain, on the north side of the Snake River west of Minidoka Dam and Lake Walcott. Extensive irrigated farming of the North Side Tract occurs on alluvial soils between Minidoka, Rupert and Heyburn. To the north, across the Union Pacific mainline are Quaternary basalt lava flows, heading toward Craters of the Moon to the northeast. This country is empty sagebrush desert.
