Formula
FeO(OH) (RRUFF)
Locality
south Socorro, Socorro Co., New Mexico, United States

Although the exact locality is not yet been disclosed, this specimen was self-collected by RJ Waidler generalized as "south of Socorro". It is much like those of Egremont, Cumbria, England. The descriptive habit is perhaps "reniform" or grape-like. Crossed sections show a dense rusty red or orange concentric nature. Very heavy, so extra shipping may apply.
