East coast: Stonybrook, NYU, Columbia, Yale, Princeton, U. Penn, Penn State, all have well-respected programs.
If you're willing to look in the midwest as well, there are some great Geology programs there: U. of Indiana-Bloomington, Purdue, U. of Chicago, U. of Illinois-Urbana Champagne, U. of Michigan, etc.
I'm sure I'm not remembering all the good programs off the top of my head, but there are a lot of decent ones out there. Any program with a lot of faculty (10+ by Geology standards) is probably successful. You can also pick based on your areas of interest...field studies, environmental, paleo, etc. etc. Feel free to post a follow-up question if you want more info! Good luck.
