Three essentially solid specimens of vivid yellow carnotite from the classic Uruvan District, Montrose County, Colorado, USA. Quite HOT, meeasuring ~150,000 CPM on my Ludlum Model 3 Counter with the 44-9 probe. Very nice high-grade uranium ore specimens for this famous uranium/vanadium mining area of the western USA. Rare!
