Anyone know the history and location of these old tanks in Allegheny National Forest?

Nothing better than a crisp October weekend in the woods

This was a beautiful 60+ mile ride through Adams and Cumberland county. Saturday was certainly approaching peak fall colors, but the area will still be prime for leaf peeping for several more days! Some of this route will take you through Michaux State Forest where the roads can get a little rough so something with ample ground clearance is highly suggested. The view from Hammond's Rocks is simply incredible! I've included a link to the route folder which starts and stops from the Gettysburg WWII Experience museum, which is a worthwhile visit, and has a cafeteria and restrooms. There are also restrooms at the King's Gap Environmental Education Center and Mansion. Enjoy the ride!
