The Concert Hall: soda straw stalactites and a rimstone pool

The Concert Hall is more than 100 feet long. Its ceiling sparkles with water drops hanging from the tips of hundreds of soda straw stalactites, thin hollow tubes of calcite.

At the far end you reach Rainbow Falls and a rimstone pool. Each drip from the ceiling carries a little calcite, and that calcite builds the pool's small dam. Look for the Lost City, the Witch's Boot and Methuselah's Birthday Cake along the way.

There were some seriously cool and unique formations I'd never seen so wonderfully preserved.
