Be-F pegmatite located near Yucca Valley, California. The mine was worked by hand for numerous years employing small jack-hammers at times. More recently it has been worked with large track-hoes. There are two types of cavities at the mine: quartz + potassium feldspar + albite (cleavelandite) and those that also contain white mica +/- aquamarine +/- colorless topaz. Most aquamarine and topaz crystals show significant etching. The California Blue Mining Claim, was deemed abandoned/forfeited in 2021 by the BLM (Bureau of Land Management) and the land had previously been withdrawn after location of the claim, meaning that no new mining claims could be located on the deposit or area due to inclusion within the "Sand To Snow" National Monument.
