The First Room: where the cave opens up

Two more flights of steps bring you to the cave floor, with the ceiling about 20 feet above. The First Room is mostly a gateway: from here the tour reaches the rest of the cave.

Keep looking up. Fossil crinoid calyxes, the remains of sea animals from the ancient ocean that laid down this limestone, are recorded in the ceiling near the start of the tour. Exactly where is a small mystery. The old record says the First Room, some longtime visitors remember them by the Upside Down Well, and the staff are still looking.

What to know

  • Two more flights of steps lead down to the floor, and the ceiling is about 20 feet above.
  • Fossil crinoid calyxes are recorded in the ceiling near the start of the tour. Their exact spot is not confirmed.
  • The room is mostly dry.

Visitors say

Lots of great formations and the fossils on the ceiling are really cool if you can find them. We will be going back again for sure.
