1990 Map of Sharp Ridge

USGS Topo · Published 1990

About this map

Umatilla National Forest and Malheur National Forest meet in this high-altitude landscape of Grant County, where the terrain is defined by the prominent Sharp Ridge. This 1980s-era survey reveals a network of meadows and seasonal water sources that supported early high-country industry and livestock. The Keeney Mine sits near the northern boundary, while a Quarry is located further south near Dishpan Spring. In the southwestern corner, the Middle Fork John Day River provides the primary drainage for a series of creeks including Dairy Creek and McKinney Creek. The map identifies numerous family-named landmarks such as Keeney Meadow, Reynolds Meadow, and Gibbs Meadow, offering vital location data for researchers tracing land use and grazing history in the Blue Mountains region.
