Spelunkers Play Cave Crystals Like a Harp
While inside the Crystal Cave, spelunker CaveChronicles and the ActionAdventureTwins came across a wall of Aragonite and gypsum needles, both crystals that they played like a harp with their hands. The crystals let out a calming, tinkly sound that’s reminiscent of magic crystals in art, music and video games.
Here’s a behind-the-scenes tour of the Crystal Cave from the Sequoia Parks Conservancy.
