1994 Map of Mount Tom

About this map

Mount Tom and Mt Humphreys tower over this high-elevation landscape on the boundary between the Sierra National Forest and Inyo National Forest. This 1994 revision captures a specialized industrial footprint amidst the protected peaks of the John Muir Wilderness, most notably the Pine Creek Tungsten Mill and an associated Tungsten Mine. These features reflect the region's mid-century mining legacy, persisting long after the wilderness designations of the 1960s. Below the granite walls, French Canyon and Humphreys Basin are defined by a dense concentration of glacial tarns, including Desolation Lake, Steelhead Lake, and the aptly named Honeymoon Lake. The map details the transition between Inyo and Fresno counties at Pine Creek Pass, providing a clear record of the trails and water systems like Morgan Creek that supported both resource extraction and backcountry exploration in the late twentieth century.
