    Drop

This is the biggest mandatory drop on the trail. a large round boulder drops you down to a pretty nice runout, but it is a good drop. The rest of the trail is pretty rocky, but typical of the other options. It is the drop that makes this expert

      Good sized drop, great for progressing up from the regular black line and thus appropriately rated as a double black. Guys saying it’s easy and should be rated lower are just insecure about their tiny little peen.

      Single Black Feature. A tiny push at the top and pretty much a roller.

      Awesome drop, definitely appropriately rated just because of the size. Fairly easy drop from a technical aspect making it a good one for someone to step up their game. Great landing and runout
