Calf Mesa, Part 4, Minerals
For a fairly complete list of minerals from the “Dexter Group” of claims see Bullock, Kenneth C., “Minerals and Mineral Localities of Utah” Utah Dept. of Natural Resources Bulletin 117, 1981. Of primary interest are sulphates that occur in micro to small thumbnail sizes such as coquimbite, roemerite, voltaite and others in association with alunogen, halotrichite, jarosite and a mix of massive, soluble, crystalline sulphates. Uranium minerals are present but were not seen as ‘collectible’ specimens.

For picture of some of these species see location references in the MINDAT database at www.mindat.org
