lava tube cave


Lava tube cave in the Lava Beds National Monument (California).­

This one was called "Catacombs", and there was a sign indicating that it was closed due to "possibly unsafe conditions".­ I think that they are just afraid that visitors could get lost, since this lava tube has a maze of branches and is rather large.­
