Calcite, Hyalite Opal, and unknowns; Coyote Hole, NV
Coyote Hole is relatively unknown to the fluorescent rock world, but clearly has some interesting material. Here is a piece that appears to have calcite, hyalite, and an unknown blue material. Some of the calcite, may actually be barytocalcite, but more study and collection is needed. Coyote Hole is in the Silver Peak District, Esmeralda County, Nevada, a relatively difficult place to get to several hours north of Las Vegas. The piece is shown here in SW, MW, LW and natural, and measures about three inches across.
