The Mad River and its numerous forks carve through this section of the Six Rivers National Forest in the mid-1950s. High ridges such as Bradburn Ridge and Horse Ridge overlook a landscape dotted with remote ranches and small mountain settlements. The isolated community of Kettenpom sits within the Kettenpom Valley, supported by a nearby Landing Strip. Further south, the map details the Island Mtn Mine near the banks of the river, a notable industrial site in an otherwise agricultural and timbered region.
