1967 Map of Harry Canyon

About this map

The White Knob Mts dominate this mid-1960s landscape, where drainage patterns define the geography of the Challis National Forest. The Big Lost River winds through the northern portion of the quadrangle, joined by numerous tributaries including Burnt Creek and Garden Creek. Human activity is concentrated along the river valley and forest access routes, indicated by the Wildhorse Guard Station and a nearby Radio Facility. A remote Landing Strip Road and various jeep trails underscore the area's importance for forest management and backcountry access during this era. Topographic details reveal a complex network of canyons such as Harry Canyon and Wildcat Canyon, illustrating the high-elevation terrain before modern developments. The presence of a Gaging Station on the river suggests a reliance on monitoring water resources in this part of Custer County.
