Comment: A floater cluster of over a dozen intergrown, euhedral calcite crystals, with natural sand inclusions. These weird calcites are very distinctive from this locality; American classics! Now seldom seen as much of this area is within a national park and collecting is prohibited, they were collected heavily in the 1960s-1970s I am told. This is a particularly large and sculptural cluster. According to MINDAT: the site is a National Natural Landmark (NNL) and is closed to collecting.

Minerals: Calcite (CaCO₃)
