Mountain Dell is the only ski venue in Salt Lake City that sets track daily. We average about 90 days of set track each winter. The ski track at Mountain Dell is created and maintained through the volunteer efforts of the TUNA Mountain Dell Grooming Crew. The crew strives to set fresh track, skate and classic, each day that there is sufficient snow coverage. That usually means the track is reset every 24 hours, although during a storm cycle the track is often set twice in one day.
