1990 Map of Sheep Ridge

USGS Topo · Published 1990

About this map

Malheur National Forest spans much of this landscape in the late 1980s, dominated by the massive profile of Rudio Mountain. This high-country terrain in eastern Oregon is defined by steep ridges and deep drainages, where seasonal water sources like Willow Spring were vital for the early ranching operations that utilized Rudio Meadows and McGarr Meadows. The network of trails and unimproved roads shown here reflects the region's history of land use for timber and grazing, connecting remote points like Timber Basin to the broader valley.
