Loren Rausch leading the last pitch of Panthalassa during the first ascent (Bridget Belliveau at the belay)
Drawn topo.
The route as seen from the main approach trail. The start of the first pitch is obscured. The red circles are anchor stations.
Looking up at P3. Trends left from the belay.
We mistakenly moved the belay to these anchors only to realize we needed to traverse this nice ledge to another set of anchors where climber is standing. These anchors are used to rappel from on the way back down.
Looking up at the very short final pitch. Single bolt and then you pop over the ridge into a very small and uncomfortable bowl. It's enough to change shoes to begin your rappels, but adds a lot of hassle.
Looking up at the stellar 4th pitch. Great pockets and that flake is way better than it looks.
