About this map

McHan Reservoir and its namesake McHan Dam dominate the upper drainage of this high-desert Idaho landscape, where water management is the primary driver of the terrain's utility. The drainage network is complex, featuring McHan Reservoir fed by Spring Creek and the long course of Schooler Creek winding through the center of the sheet. Notable landmarks like Flat Top Butte and Johnson Hill rise above the drainage systems of Black Canyon Creek and Thorn Creek.

Settlement is sparse, represented by the Fir Grove Ranch near the western edge, connected by a network of unimproved roads including Fir Grove Rd and City Of Rocks Rd. The map records numerous water sources vital for ranching and wildlife in this arid environment, such as Hash Spring, Mud Spring, and Gwin Spring. The intersection of these natural springs and intermittent creeks defines the local geography and historical land use patterns.
