Ilgenstein Rock is a long ridge with good views that extends from Bear Swamp Lake to the North Cape on Pierson Ridge. The actual summit of Ilgenstein Rock is just North of the viewpoint along the Hoeferlin Memorial Trail.
The photograph above was taken from the North shore of Bear Swamp Lake.
One of those nice summits typical for NJ. It's not the overlook but some rock rolled over in the bush some hundred yards away. Great view of Drag Hill from that overlook though! And THAT, was a tough climb.
