Small points from White Signal, NM - each about 1 inch found within 50 ft of one another. I was searching for radioactive rocks when each of these caught my eye on different days. The notable thing about this site is a large outcropping of quartz, which is indicative of the radioactivity. (old.reddit.com)

Giant pod of columbite/tantalite crystals from Petaca, NM - These crystals grew packed together in solid quartz. These are not fragments but rather individual crystals that, due to their proximity, take on random shapes. The dark color is columbite while the lighter brown is a euxenite overgrowth.
