When I hiked through there in 2002 the Sarver Hollow shelter was brand spankin' new. The roof of the old homestead cabin looked like it had just recently caved in and the walls and chimney were still intact, minus a couple of logs that some campers had removed to use as benches around the fire pit where people camped next to it. The shelter was built to discourage people from camping near the cabin. There was also a smaller structure that people referred to as a chicken coop. I stand by the assertion that the rock piles were made to make room for apple trees. This has been discussed on this forum several times over the years and this is the only explanation that wasn't blind speculation without anything to back it up.
