About this map

Little Lost River Valley provides a clear perspective of this high-desert drainage where the Little Lost River meets several significant mountain tributaries. The map shows a landscape defined by alluvial bars and flatlands, most notably Mulkey Bar and the higher-elevation Mud Flats and Deer Flats. These level reaches served as critical anchor points for transportation in a region otherwise dominated by steep terrain, as evidenced by the convergence of the Little Lost Hwy, Pahsimeroi Rd, and Summit Creek Rd.

Hydrography is a primary feature of this 2013 survey, detailing the network of seasonal and perennial waters such as Wet Cr, Dry Cr, and Sawmill Cr. The northeastern portion of the sheet reaches into the protected boundaries of the Challis National Forest, where smaller springs like Willow Springs and Magpie Springs emerge from the slopes above Basinger Canyon. For those studying the geography of Custer, Butte, and Lemhi counties, the map preserves the exact alignment of these county lines as they intersect the valley floor.
