Located high above the surrounding limestone sinkhole plain, Onyx Cave is a system of vertical shafts uncovered during construction of the Guntown Mountain parking lot on Huckleberry Knob. The pits and domes of Onyx Cave were protected from weathering by the knob’s sandstone cap rock and after their formation slowly became coated by calcite crystal flowstone. The combination of crystals and seeping water makes the walls of this most unusual cave shimmer.
