Black Chasm Cave
From Wikipedia, the free encyclopedia
Black Chasm Cave, near Volcano, California, was assigned National Natural Landmark status by the National Park Service in 1976. It was recommended for this protection by members of the National Speleological Society who had made explorations of its numerous chambers in the 1960s.
One of the outstanding geological features of this cave (and a major reason for its NNL designation) is the profusion of helictite crystals located in the Landmark Room. These unusual speleothems or formations are probably created by hydrostatic pressure (although there is still some speculation on the exact cause) resulting in horizontal orientation.
