Talk about skippy rocks, I just saw it again since I was driving to Toronto last weekend. There's an interesting rock formation you can see from the N.E. Extension of the PA Turnpike just as you exit the Lehigh Tunnel northbound. It looks like a giant wall of boulders extending east-west quite a distance. Some boulders are a couple feet in diameter, others larger than a car. The long wall structure always made me think it was a moraine formed by advancing glaciers during the last Ice Age, but I pretty much made up that explanation so I'm looking for official confirmation of what the rock formation is. My other idea is that it might be the Great Wall of Pennsylvania built to deter the attacking forces of the barbarian New Yorkers from the north. uncle phil might know this since he's one of them.
