Old stock bat cave jasper from Central Oregon. This rough was collected from the cave in the 1970s. One walked about a 1/2 mile up a talus slop. Always on the look out for rattlesnakes, occasionally kicking one out of the way. When you get to the base of the cliff, you climb up about 20 feet. When you have entered the cave, you chase the bats out and begin looking for jasper. The process is repeated on the way down the hill, hopefully with some jasper in your pack The cave is now on private property and is no longer accessible. The jasper takes a great polish. One should be cautious when polishing not to allow the stone to get too hot, as it will fracture.
