It is located in Coal Township PA Near a mining patch town called Bear Valley on private property owned by Reading
It is in a relatively baron are of strip mined land and is hard to just head back and find it because of the steep cliffs and regrowth in the area, it's a rather intimidating landscape but if you found someone who knows where its at, it is very accessible and you can apply for a free permit to access the grounds on the Reading Coal Homepage .
Several Times a year groups of geology students come and study the formation
Maybe one of the members of Abandoned Mine Research, Inc.
