2011 Map of Jerry Peak

About this map

Jerry Peak dominates this high-elevation terrain in Custer County, where the hydrological network of the Big Lost River basin begins its descent through a complex system of canyons. The map documents a landscape defined by seasonal drainages and permanent water sources like Howell Spring, which likely served as a critical waypoint for early high-country ranching and travel. This 2011 survey reveals how the environment is carved by the Pinto Creek and Sage Creek systems, with landmarks such as Sawmill Canyon and Pecks Canyon suggesting a history of local resource extraction and early settlement patterns. To the east, the isolation of Swensen Basin provides a view into the remote grazing lands and wilderness character of central Idaho as it appeared in the early 21st century.
