This shot from the slopes of Kangaroo Ridge doesn't show the route, but gives an idea of the short, direct approach. Liberty Bell's E face is near the center of the picture. Left of its lower half, Minuteman Tower is partially illuminated, surrounded by shade.
The pond beside the highway is just hidden by the tree branches at the right side of the photo. Park there, hike up through the woods, then up across the talus slope to the left corner of Minuteman's base.
Photo is from early October.
