Open-File Report O-08-04 PRELIMINARY GEOLOGIC MAP OF THE LITTLE CHINQUAPIN MOUNTAIN 7.5’ QUADRANGLE, JACKSON AND KLAMATH COUNTIES, OREGON
The Little Chinquapin Mountain quadrangle (LCMQ) has as its focal point Johnson Prairie, a broad, relatively flat, sediment-filled basin that is cut diagonally from the northeast to the southwest by Johnson Creek. It is a savannah with some scattered trees but is mostly unfenced pastureland for range cattle and a sizable herd of elk in the summer months. To the southwest, Jenny Creek, formed by the confluence of Grizzly Creek and Soda Creek in the west-central part of the LCMQ, acts as a crude boundary between regions with different geomorphology. To the east and north of the Soda Creek-Jenny Creek stream valley, all the outcropping rocks are less than 5 million years old. To the west and south, the surficial rocks range in age from approximately 23 to 1 million years old. 2008
