I Got Rocks In My Head!

This is an on-going study of rocks, waters and trees by Indian Rd at Inwood Park in the most northern tip of Manhattan. The Columbia Football Stadium is right nearby as well as The Henry Hudson Bridge is, by these waters. According to Sidney Horenstein, geologist with The American Museum of natural History, "There's no better place in the city to see its geology in all its relationships."

There are exposures of Inwood marble, outcroppings of Manhattan schist, boulders of billion year old Fordham gneiss and glacial striations and potholes. These are no ordinary potholes! It was only 15,000 years ago that the striations and potholes appeared during the last Ice Age (turning 60 doesn't feel so bad after all) The potholes of Inwood Park were carved by violent prehistoric whirlpools of melting ice and rocks that drilled deep cylindrical holes in the rocks. Even some of the many trees and flowers in the park, are no longer extant anywhere else in Manhattan.

I have a whole new way of looking at rocks and trees now. Some of the most basic and raw things around us, have a life and history that is astounding!
