April - welcome to DCski. You should check out the resort listings at http://www.dcski.com/resorts/index.php
to get an idea of the resorts "in the area" (some are obviously closer than others).
In terms of the closest ones to DC, I'd say the three closest are probably Liberty, Round Top, and Whitetail, although Bryce may be closer. That's an uneducated guess, of course, and "closest" doesn't always mean "shortest trip to get to".
Are you coming from the city itself or a suburb? Sometimes a few miles one way or the other can have a pretty dramatic impact on travel times...
As far as I know, there's nothing that's within an hour of downtown, but you should be able to get to a few of them within 2 hours' drive.
