FATMAP difficulty grade
Right next to the famous Corbet's Couloir, this run is named for local legends John Simms and Charlie Sands, the first two to ever descend it, and who did it first is a secret they've never shared. This inbounds run is so insane that, unlike Corbet's, you need special permission from the Ski Patrol and to sign a waiver to attempt it.
If you do get that permission, it will quickly become clear why they're so strict about allowing people to ski it.
While Corbet's has several entrance options that vary by season and conditions, the only way into this beast is a narrow entrance that requires a 90 degree turn in the air as you fall 20+ feet into the very narrow slope.
Make sure to stick the landing and avoid the walls or you will likely suffer some serious injuries.
Once you're in, enjoy the powder as the run rapidly opens up and merges into Corbet's Couloir.
