A lacustrine Ca-gypsum-halite-Sr deposit/mine located in 27, T5N, R12E, SBM, 5.3 km (3.3 miles) SSW of Saltus, on the dry lake, on federal land (federal lease/located claim). Owned & operated by the Leslie Salt Company (100%), Clifornia (1990). MRDS database stated accuracy for this location is .
NOTE in USGS MRDS database file: Although the calcium and sodium chloride, gypsum and celestite (Sr) occurrences are spread over different localities, Bristol Dry Lake is treated as one mineral locality, zoned with respect to concentration of brines and evaporites.
NOTE: The geographic coordinates presented in the USGS MRDS database file (34.57502, -115.72054), are in error and place this locality N of Amboy and far from the dry lake. The geographic coordinates presented in this Mindat file are the coordinates of record for sec. 27, this township and place the locality at the commercial salt harvesting operations.
Local rocks include Quaternary alluvium and marine deposits.
Workings include unspecified surface and underground openings (surface salt evaporators are prominent on the topo map).
