1987 Map of Mulkey Bar

About this map

Challis National Forest borders the northeastern corner of this high-elevation desert landscape where the borders of Butte, Custer, and Lemhi counties converge. The terrain is defined by broad alluvial fans and basins, including the namesake Mulkey Bar and the neighboring Deer Flats and Mud Flats. Water management is central to the human footprint here, visible in the network of irrigation and transport features like the Dry Creek Canal and Black Ditch that draw from the Little Lost River and its tributaries. These waterways, alongside Wet Creek and Sawmill Creek, suggest a complex history of ranching and agricultural efforts in an arid environment. Small-scale resource extraction is also noted by a Gravel Pit, providing evidence of local infrastructure development within this expansive valley system.
