Natural Uranium Rock URANINITE Weight: 4.5 Oz. Radioactivity: 36,900. CPM (counts-per-minute) $24.00 plus $10.50 shipping This rock was recovered from the wild during July 2025, from Jurassic Canyon, near Grants NM. This canyon is the richest uranium field in the USA, and fourth richest worldwide. Each year, I escort 3-4 visiting rockhounders for a 3-5 day outing to the canyon, located 18 miles from the town of Grants NM. It has been claimed that the NM Mining Museum, located on Santa Fe Avenue at the center of the business district, is the only museum worldwide that devotes itself to entirely to uranium, and not to other minerals. URANINITE ore is most abundant at the mines in the Czech Republic, located to the south of Germany. Here in the USA, uraninite is found mostly near CHARLEY STEEN's famous mine of the 1950s and 1960s, the MI VIDA MINE, 40 miles S.E. of Moab Utah. Even when one digs through the waste piles near the mines out there, there are plenty of radioactive uraninite rocks waiting to be found. Charley Steen, known as the HERO OF URANIUM MINING, was a whiskey-drinking Texan. His affinity for whiskey did not go well with the non-drinking local LDS population at Moab. But Charley Steen was well liked because his mines brought local employment to Moab. Steen also donated generously from his personal uranium fortune, to support Moab's local charities. Steen also served two terms in the Utah State Senate, located at Salt Lake City. $24.00 plus $10.50 shipping Stephen Buggie, Ph.D. Professor Emeritus / Rock Hound "Have geigers, will travel" Univ. of New Mexico, Gallup
