Extremely steep trail. Like, really really steep. Literally 47 degrees at its steepest(how do you think it got the name?). Expect tricky switchbacks, steep chutes, and off-camber sections. Did I mention it's steep? Once you get through the top section, it's possible to find some flow in the very well-built berms. At this point, you'll be rewarded with a pack of very fun jumps, ending with a massive left hip and a mellow traverse back to 286. Sketchy at best, nearly impossible at worst. Depends on the conditions. Best ridden the day after a rainstorm.

Access Info

From the intersection of Lower Ridge and Deadass, go straight up a small grade reversal, stopping before the intersection with Upper Skinny Pete. Look to your left, and it'll be there.

This trail is unsanctioned.
