A large, very rich specimen of colorful secondary uranium minerals including Johannite and Zippeite on Uraninite from a super classic southern Utah locality. Very nice example of this quite uncommon material. Quite HOT too, measuring ~160,000 CPM on my Ludlum Model 3 counter with the 44-9 probe. Rare!!
