Satellite image photograph of eastern Idaho. The view extends from near Mackay in the upper left, to north of Burley in the lower left, Malad Summit in the lower right, andHeise in the upper right. American Falls Reservoir is in the lower center, surrounded by irrigated farmland. The black splotches on the Snake River Plain are lava flows, with Craters of the Moon in the middle left, the Great Rift in the lower center, and Hell's Half Acre in the upper right center.
