2013 Map of McHan Reservoir

About this map

Mount Bennett Hills and the striking geologic formations of the Little City of Rocks dominate this high-desert landscape in Southern Idaho. The map reveals a drainage network defined by McKinney Cr, Schooley Cr, and Thorn Cr, which cut through deep ravines such as Burnt Willow Canyon and Rattlesnake Canyon. This area is marked by numerous water sources critical for high-country grazing, including Hash Spring, Mud Spring, and Bull Spring, alongside the McHan Reservoir in the northern reaches. The Camas and Gooding County boundary bisects the quadrangle, primarily following Fir Grove Rd, while prominent landmarks like Flat Top Butte and Johnson Hill provide orientation across the sagebrush-dotted terrain.
