1985 Map of South Chapin Mountain

About this map

North Chapin Mountain and South Chapin Mountain dominate this mid-1980s landscape in Cassia County, defining a rugged drainage system characterized by deep canyons and seasonal water sources. The complex topography of Heglar Canyon is further divided into North Heglar Canyon and the truncated South Heglar Canyon, illustrating the intricate natural channeling of this high-elevation terrain. On the lower slopes and valley floors, Butler Spring and the headwaters of Shirley Creek and Warm Creek provide critical water points in an otherwise arid environment. A single Gravel Pit indicates local small-scale resource extraction, but the primary character of the map is one of remote, undeveloped land typical of southern Idaho's mountain ranges during the late 20th century.
