Finally got to check out Hole in the Wall. Water flows up from under the rock face. Not quite sure what's going on to make it happen, but I'll definitely be doing some research. It's probably the only place I would be comfortable drinking the water in the area that is rift smack dab in the middle of coal mines and oil and gas. I'll get better photos next time. I only had a few minutes before the next truck was going to come barreling down the road.
