That rock is called Fordham gneiss!

Fordham gneiss is one of the coolest—and oldest!—rocks in all of NYC. It was formed around 1.1 billion years ago, in the pre-Cambrian era, before even the first multi-celled animals appeared in the fossil record! So next time you see some Fordham gneiss, be sure to give it a pat and say, “Nice to see you again, old friend.”
