I am not aware of any alpine glaciers documented for this part of PA, and thus the deposits on and topography of Jack's Mt., if glacially related at all, are most likely due to frost action associated with glacial fronts over a 100mi to the NE.
I am for PA and have studied the mountains quite a bit, Jack's Mountain form the flat's by Mount Union High School's playing fields (520 ft.)to the top off the 2321 foot summit is the highest elevation gain in the state. I always judge a mountain on its true size from bottom to top... By the way, North Mountain in Sullivan county close to Muncy Valley (Although higher in elevation at 2600 ft.) is a close second
