Very nice formations of Andersonite. Not usually seen as crust is more common. Decent reading due to the Uraninite in the sandstone. A bit over 100,000 cpm on Radiacode 110
Everyone seemed to be building their glow collections so I am offering some of my better pieces with UV reaction upon request!
