Many janky drops into sharp corners make this one of the most technically challenging trails to clean on the mountain. The trail is also quite thin, so bars may clip trees. This trail should not be hidden on the map.

Access Info

For some reason it is listed as a hidden trail, but it is not. Just head straight at the wide right hand turn when coming down Historic Trail. The trail is supposedly closed at the bottom due to "hazardous conditions", but the trail itself is fine and fully open at the top.

This trail is unsanctioned.
