Great story - never heard of the PA Grand Canyon before. Most of the mountain tops in the Adirondacks are bald rock, where you can see the striations from moving glaciers dragging rocks with them under tons of pressure. Same in Mt Rainier Nat.Park. In eastern Washington, a similar event happened when an ice dam was breached and the Grand Coulee was formed. In Western Oregon, we have the 'Willamette Rock' - a huge boulder of Rocky Mt. granite washed down through the Columbia Gorge by sitting on top of an iceflow, deposited in the valley when the flood subside and the ice melted.
