We didn't have a thermometer, but we estimate it was something like 22° during the day, and maybe 8-9° at night. We kind of lucked out with the weather, because it was considerably colder both before and after our weekend of Jan. 17-19. Strong winds with blowing and drifting snow moved in the morning we packed out. To quote one of the leaders of our group "I think that's it for lean-to's" Hahahaha. A number of us are in our 60's, so we are going to build a better shelter and make our trek in, pulling toboggans, shorter. As we like to remind ourselves, "we are here to have fun and learn something, not die or get hurt".
