1986 Map of Potter Mtn

About this map

The Calapooya Mountains and the high ridges of the Cascades define this mid-1980s landscape, where the North Umpqua River and Clearwater River carve deep drainages through the Willamette and Umpqua National Forests. The map reveals a high-elevation wilderness managed for both recreation and resource utility, featuring the isolated Winter Night Camp and the notable Umpqua Hot Springs. Evidence of water management and power infrastructure is clear at the Deer Creek Diversion Dam and Clearwater Forebay No 1, which utilize the area's steep gradients. Natural landmarks like Potter Mtn, Watson Butte, and the Mowich Cave stand alongside numerous quarries, indicating active land use within the rugged volcanic terrain of the Watson Ridge and Dread and Terror Ridge systems.
