Diamond Back is two different trails, depending on grooming or not, and what time of year.
When this is groomed, this is a great, medium steep, fun black on the back side of Dercum Mountain.
This is quite fun if you are one of the first down it when groomed, or even on a powder day.
When it’s bumped up, it’s a very long bump run that can take you a long time to get down depending on your proficiency.
Check the grooming report to see if they have groomed it to decide.
The sun and snow depth also are very important as it can get scraped off and/or have soft bumps.
