|Location and accuracy||Site is at an elevation of about 4,800 ft. on the north side of a large, east-southeast-flowing tributary to the upper Wind River about 5 miles north-northeast of the head of Beaucoup Creek (SE1/4 sec. 18, T. 13 S., R. 20 E., of the Umiat Meridian) and approximately 2 miles northwest of the Occasional Group (PS011). Location accurate within 1-mile radius.|
Geologic descriptionVisible sphalerite and galena occur in a stratabound quartz-calcite vein (Menzie and others, 1985). The vein cuts black, recrystallized chert and chert breccia which is found at the top of the Devonian Skajit Limestone. Barker (1978) reported sulfides as disseminated crystals and veinlets in limestone and dolomite in creek rubble. Anomalous values of silver, arsenic, antimony and cadmium were noted in rock samples from this location. The bedrock is mapped as Skajit Limestone in contact with calcareous sandstone member of Hunt Fork Shale and/or Beaucoup Formation. No other descriptive information is available.
