Geology Q for area just north of Seneca Rocks

What type of rock is that way up on the high ridge off to the right as you drive north away from SR? It's very impressive in the late day sunshine. It seems to be the same band that descends to road level around the Smoke Hole development. Given that there's a cavern there, I am guessing it's limestone.

And the obvious follow-up: any climbing potential on it?

(I know, the obvious answer is "Why would you bother, with Seneca Rocks there?")
