Peakbagger is a great site. No I haven't been to that exact spot, which is right near the point where Lancaster, Lebanon and Berks Counties all meet, but I have been to some other high spots up in the Furnace Hills. A buddy and I once backpack camped up there on a high hill then hiked down to fish for opening day trout (believe it was Hammer Creek). We were probably at ~1,000 feet. Beautiful area up that way, as @GrandmasterB knows all too well.
