As markv says, VFTT is a great resource ... I've been a member there for quite some time. Unfortunately, for a variety of issues that have come up over the years, the owner of the site now requires new members to be sponsored by a current member ... preferably with the two actually knowing each other.
I did a north-to-south summer traverse about five years ago. And while it was a cool thing to do, a winter traverse is in a different league. Most folks go north-to-south in either winter or summer since the southern part of the traverse is much easier to tackle when tired. Also, if you are blessed with good weather and conditions, it is not uncommon for winter climbers/hikers to make better time than summer hikers across the range as the terrain can be much less rugged when smoothed over by ice and snow.
Here is a link on VFTT to a traverse completed by Tim Seaver including another link to pictures from his own site:
FWIW, Seaver is a stud who is well-known for his accomplishments in the Northeast ... so individual results may vary. Fitness is key. Good luck!!
