Starting from the prominent gully north of the main Mt. Winchell formation, ascend the left-hand arete to the north summit.
Descend by traversing the crest south to the gully separating the significant, yet un-named, summit from the main formation.

Approach from South Fork trailhead to Bishop Pass. Contour SE above a bench to directly below west side of Mt Winchell and Thunderbolt Peak. Hike up meadow and talus left of white rock band then angle up and right to the toe of the flat arete at the top of the talus cone.
This description is a bit vague but this is how we climbed the arete. Great climb named after my daughter. Worthy of some repeat visits and there seemed to be plenty of new route potential in the basin.

P2 climb up face and then arete angling slightly left to small ledge. 175ft, 5.8
P3 Traverse right around bulge then up groove and steep corner. 150 ft, 5.9
P4 Climb crack and blocks to top of first tower. 50ft, 5.5

P8 climb up 5.7 cracks then stem 5.9 corner. 150ft 5.9
P9 Travers to the right of arete with a step down. 60ft, 5.9
P10 climb up obvious crack to a steep corner with 5" crack. 150ft, 5.9.
