Reconnaissance geochemical survey of gully and stream sediments, and geologic summary, in part of the Okanogan Range, Okanogan County, Washington
A reconnaissance geochemical stream-sediment sampling survey was conducted in a 1,150-km 2 (440 mi 2 ) area in the central part of the Okanogan Range, adjacent on the west to a 2,000-km 2 (800 mi 2 ) area previously studied. About 75 percent of the bedrock is composed of a mosaic of elongate northwest-trending Mesozoic plutons, the average composition of which is probably granodiorite. These intrude a highly recrystallized eugeosynclinal assemblage of Paleozoic and Mesozoic age that makes up about 15 percent of the area. The remaining 10 percent consists of andesite and dacite flows and flow breccias of Tertiary age that unconformably overlie the older rocks. The entire area is irregularly mantled by glacial drift.

Distribution of copper and other metals in gully sediments of part of Okanogan County, Washington
A geochemical exploration program aimed at determining regional patterns of metal distribution as well as pinpointing areas likely to contain undiscovered ore deposits was carried out in north-central Okanogan County, Washington. About 1,000 gully and stream sediment samples were collected from a rectangular area of about 800 square miles. The area includes two contiguous, virtually dormant, mining districts that had yielded nearly $1.4 million in gold, silver, lead, copper, and zinc prior to the end of World War I, mostly from quartz lodes.

Cenozoic Volcanic Rocks of the Devils Postpile Quadrangle, Eastern Sierra Nevada, California
Cenozoic volcanic rocks of the Devils Postpile quadrangle are of late Pliocene to Recent age and are divided into 11 map units. The suite is alkalic-calcic and ranges in composition from basalt to rhyolite. It includes a rhyolitic welded ash-flow tuff which is probably correlative with the Bishop Tuff, although the two units are geographically isolated by the Sierra Nevada drainage divide. The Devils Postpile itself is a classic example of columnar jointing in the lower part of a lava flow.

Geologic quadrangle maps of the United States: geology of the Casa Diablo Mountain quadrangle, California
The Casa Diablo Mountain quadrangle was mapped in the summers of 1952 and 1953 by the U.S. Geological Survey in cooperation with the California State Division of Mines as part of a study of potential tungsten-bearing areas.
