Copy what T Roper said about Massacre. The walls can stay quite warm and favorable through the winter if the roads stay navigable.
There is a decent group of climbers at ISU, including an active climbing club. You might try to get in contact with them. The Outdoor Adventure Center, OAC, sets up a weekly climb on Thursdays until the weather turns wet.
If you need a partner, send me a message. I am pretty busy in grad school, but I can get away every now and then.
