Park at a small pulll off just north of the North Fork of Bairs Creek. This is located off foothill road.
There are several ways to go - but the way that seemed to be only less tortuous than the rest is to follow the ridge on the north side of the creek sometimes going on the north side of the ridgeline itself. It is a bit sandy but less treed. Aim for the top of the ridgeline, then traverse west without losing much altitude (this is the worst part as it is sandy and treed). Aim for a notch in a ridge with some trees on it. Continue traversing past the notch to the creek where it forks - cross where convenient. Follow the ridge on the north side of the south fork up to the snow line. Then follow the drainage up to the Grand Cirque. Continue up the cirque to the headwall and hike up the headwall. The top of the headwall is 13,000'. Continue up another cirque to the north to the summit plateau and on to the summit. Because of route closures, you have to go earlier in the season. Bring skis - this is a nice ski down from the summit (literally) to snowline.
Since it's early season, go with skis and go early in the year. You may want to bring an ice axe and crampons if conditions are icy.
If you have information about this route that doesn't pertain to any of the other sections, please add it here.
