Graffiti on the walls
The first Boisean known to have explored the cave was Claude W. Gibson in 1890. “There were only three or four people that I have ever been able to find that knew of the location of the cave prior to our visit,” he explained. “After that it became quite generally known.”¹
After no small trouble finding the opening, he and a group of others positioned one of their wagon wheels over the hole with a rope as a kind of winch. “By turning the wheel one way or the other the enlarged hub would wind up or unwind the rope as required.” One man was lowered at a time until the last man, who slid down the rope.
