Approximately 15,000 years old, Bear Trap Cave is older than the Wapi flow (2270 years old) and the Craters of the Moon flow (as young as 2070 years old).

I been here many times. This spot is an area of the lava tube that the ceiling collapsed, opening up a small section. Does not go in very far. Room is rather tall. Large lava blocks to walk and scramble around. Be careful if you go in and don't get injured. I have heard people say there are rattle snakes in there. I have never seen them. Just be careful, never put your hands or feet any place you can not seen. I been around rattlers many many times. No problem.
