There's alot of interesting geology in New York. There is a place near where I grew up where the shale bedrock is exposed, and you can see the grooves cut in the rock from the glaciers.
Alot of New York was at one time, submerged. Some of the largest salt deposits in the world are buried in the western part of the state.
you can see the groves in the rocks in the exposed bedrock in Central Park and the Bronx Zoo....
Come and see my stromatolite formation that is even bigger than the "famous" petrified gardens in Saratoga...
(and it's a 1/2 million years older)
The last time I was out in Alberta I took a tour in the Canadian Rockies, and the tour guide described a recent hike up into the mountains. He said he found sea shells and other signs of ocean creatures near the top of one of the mountains -- 12,000 feet above sea level.
In upper Manhattan there's exposed mica schist also with the glacial striations.
