Rowley mine in Maricopa County, Arizona is a fascinating mineralogical site - Type Locality to 13 species, most of which are linked to bat guano. Mammothite is not one of these, and is nothing to do with fossils either, but is named after Mammoth mine. Rowley mine is the second world occurrence of this exceptionally rare, complex lead copper aluminium antimonate hydroxide chloro-sulphate. This older, large miniature-sized dense specimen has four arrows marking where Mammothite microcrystals are located, within, what appears to be a massive white Cerussite matrix containing at least one circular area of residual primary Galena. There are many other areas of blue on the surface that are not marked, and these may well be Diaboleite or something similar. This is certainly a specimen that will be of interest to rare species enthusiast's, especially those with a passion to identify some of the other interesting species upon it.
