1987 Map of Red Hills

About this map

Little Lost River Valley dominates the northeastern corner of this high-altitude landscape, where the Mud Flats meet the drainage of Summit Creek. This 1980s topographic record illustrates the transition from the distinct peaks of the Donkey Hills and Taylor Mountain into the broad, alluvial expanse of Mulkey Bar. The terrain is defined by its water sources, including several named points such as Buck Springs, Mud Spring, and Camp Springs, which suggest the historical importance of seasonal water for local livestock or travel through this arid interior. The boundary between Custer County and Butte County cuts through the southeastern section, while a network of 4wd tracks provides the only mapped access across the Red Hills and along the base of the mountains.
