1972 Map of Howe Peak

About this map

Howe Peak anchors the eastern edge of the Lost River Range in this early 1970s survey, marking a stark division between wilderness and government territory. To the west, the Challis National Forest protects high-elevation terrain carved by Sixmile Canyon and Eightmile Canyon. To the east and south, the landscape shifts abruptly into the high-desert plains of the National Reactor Testing Station. This restricted zone includes Deadman Flat and the small site at Grafton. The map illustrates the specialized land use of the era, where remote Idaho canyons meet the scientific frontier. Numerous Borrow Pits and a network of Jeep Trails suggest ongoing industrial and maintenance activity supporting the nearby facilities. Local history researchers will find the specific Restricted boundaries and infrastructure, such as the Radio Facility, helpful for understanding the footprint of federal energy research in Butte County.
