1990 Map of Eagle Rock

USGS Topo · Published 1990

About this map

The Crooked River dominates the southern landscape of this Crook County quadrangle, where the impounded waters form the Prineville Reservoir. This 1990 edition highlights the extensive public lands managed as the Prineville Reservoir State Wildlife Area and the adjacent Prineville Reservoir State Park. The terrain shifts from the canyon depths of the reservoir to the high elevations of the Ochoco National Forest in the northeast corner. Notable geological landmarks like Eagle Rock and the broad expanse of Combs Flat characterize the area's physical geography. Evidence of local infrastructure includes the Boa Ramp for water access and a small Gravel Pit near Eagle Creek, reflecting the intersection of recreation and small-scale resource extraction in central Oregon.
