Wardsmithite from Ryan, Inyo Co., California, United States

I think it is impossible to discern the Wardsmithite from a host of other white minerals on the specimen. Comparing the specimen with the main Mindat photo, the identification is reasonable. It has two older labels that state there is also Inyoite, Probertite and Ulextite (see prov. tab). It olnly occurs at the Boron deposits of California.
