We had four foot drifts at the top, 6-8 inches of snow running on sections of the trail. It just depends on where the sunlight hits the trail and yes it makes all the difference in the world because it's so slick.
We broke through one 4 ft. drift that took a little while. It's really fun when there are rocks, dirt sand AND you're on a major incline. Hummers are so great
