Devil's Playground, pegmatites
Utah

"small magma bodies intruded into the granitic rock forming pegmatites (coarse-grained igneous rocks with interlocking quartz crystals, usually found as irregular dikes or veins). The pegmatites are fairly common, several inches in thickness, and extend hundreds of feet. They represent the last and most hydrous (waterrich) portion of magma to crystallize. The pegmatites are easy to locate because they are more resistant than the surrounding rock, thus they resemble ribs and bones sticking out in relief."
