Cool map. I live right on top of a “push moraine”, which is that thick dotted line that is scene in your map, at the edge of the glacier.
I lived in Ithaca NY when I was a kid. We studied geology in 8th grade and did great field trips. I remember visiting the moraines at Cayuga Laje and seeing the striations on the rocks. I thought it amazing to see 10,000 scratches!
