Certified Ski Diva
So, my DH and I are now on Northstar's e-mail list, from when we visited there this past spring. They recently sent us an e-mail talking about their off-season activities, noting that they had the lifts running so that you could go to the top of the mountain and that dogs were welcome. This led us to a number of questions that I figured the divas would know.
Being mid-westerners with tiny little hills, these things aren't issues or questions at our local places. You can definitely walk down from the top, and they don't run the lifts in the off-season. 
In no particular order:
Can dogs ride the ski lifts? Can they ride the gondolas?
When you ride the lifts to the top of Northstar, how do you get down? Do they set it up so you can ride the lift back down, or do you end up hiking down?
If you were going to hike down, isn't it pretty steep to get back down? Or, is the slope less steep without snow than it is with snow?
