Open-File Report O-08-01 PRELIMINARY GEOLOGIC MAP OF THE SPENCER CREEK 7.5’ QUADRANGLE, KLAMATH COUNTY, OREGON
The Spencer Creek quadrangle, Klamath County, Oregon, has as its centerpiece Spencer Creek, one of the few perennial streams in this segment of the southern Cascade Mountains. Also unusual is the north–south orientation of the Spencer Creek drainage basin, specifically the John C. Boyle Reservoir, which extends from Buck Lake in the north to the Klamath River in the south. This quadrangle occupies predominantly low terrain between Surveyor Mountain and Buck Mountain to the west and the Aspen Butte-Little Aspen Butte-Clover Butte ridge to the east.
