This route starts out with a three mile push for a mortal man. Once you reach the Alpine trail it doesn't take long to see why this is a black diamond, with technical steeps and equally challenging short ups for 1 1/2 miles to the Hall Lake trail. Take a right and the trail keeps up with it's engaging narrow technical nature for about 5 miles to the creek crossing. Once across the creek the trail starts to open up and turns into a fast-flowing ripper to the end.

Alpine 7 from Six-mile to Hall still has minor patches of snow and about 8 trees across. The rest of the loop is cleared and perfect!

FAMB Trail Crew has cleared all obstructing trees (66 of them) up to the A7 intersection! There are two rootball holes created by falling trees just above the two switchbacks (around mile 3.2 from the bottom), but they are ridable with caution.
