The Heart of the Gold Country
Black Chasm Cavern
On the 50-minute guided walking tour, descend a series of stairs and walkways that loop around the formation covered caverns walls. Here, flowstone interspersed with stalactites, draperies and helictites compete for space above the stairways. In the Colossal Room, a platform seemingly suspended in midair hangs above a 80-foot drop to small glimpses of the jewel-like Lake Reflection below, made bright turquoise by naturally occurring calcium bicarbonate.
