Probably not quite a black diamond, but more than blue. Fun way down from Napalm Ridge. Near the bottom, prepare to stop and carry across the creek.

Fast and fun, with little berms and jumps.
[Reply]

Techy for the first chute and then some steep sections along with a mediumi sized double gap jump about 1/4 of the way down... Some off camber blown out sections coming out of some corners that your front tire can wash out on... Can get really flowy and super fast once you get a hang of the lines... Black diamond because of the steepness of the trail and the potential speed at which you can carry down the hill.
