Cornice at Mammoth?Curious how you think Corbett’s compares to Cornice.
No comparison at all. Cornice is a groomed black. It's one of the easiest runs off the top other than the cat track, and doable in good conditions by an advanced intermediate.
Corbett's is a very difficult trail, suitable only for experts. I don't think it's quite as difficult as it reputation ("The hardest run in North America" kind of stuff), but it is a very intimidating trail with real consequences if you fall.
Cornice used to not be groomed, and would develop a huge cornice. That was a much harder trail than today's version, but is before my time skiing there.
