A clay occurrence located in sec. 29, T7N, R9E, MDM, 1.2 km (0.8 mile) NNW of Carbondale, N of Willow Creek. Operated by the Western Refractories Co. MRDS database accuracy for this location is not stated.
NOTE: The geographic coordinates presented in the USGS MRDS database file are in error. Specifically, the longitude value of 120 degrees should be 121 degrees. This was verified through the research of the coordinates for the center of the T&R section (TRS-data).
The Yosemite No. 1 clay is in beds 8 to 9 feet thick. The Yosemite No. 2 clay, 6 to 10 feet thick, is more sandy and has lower refractory qualities than No. 1 clay. Above the Yosemite clay is 5 to 5½ feet of reddish brown, gravelly soil and below is carbonaceous clay and lignite, and then more clay. The clay beds gradually thin to the N. Local rocks include Mesozoic granitic rocks, unit 3 (Sierra Nevada, Death Valley area, Northern Mojave Desert and Transverse Ranges).
Workings include surface openings comprised of 3 large, shallow pits, only 2 of which were active in 1953.
The Yosemite clay was used primarily in the refractories at the Western Refractories Co. plant in Ione.
