While grooming in the Mt. Jefferson Snowmobile Clubs snowcat on the trail towards the Dee Wright Observatory we has the hill side near Windy Point slide onto the road behind the snowcat. This was a north facing slope, the entire slope slid but was stopped by the groomed trail. A large amount of slabs are loose above the groomed trail with minimal support.
