Here are some photos from my Tyndall climb of Shepherd Pass.
I ascended in micro spikes with trekking poles and descended with crampons and ice axe in the softer snow.
I ascended roughly along the trail route - some edges of the switchbacks are melted out in the rock patch and then tucked behind the gendarme.
On the descent I cramponed down the central line - the zip zag boot track is mine. The top section is the steepest and was a bit dicey in the micro spikes, especially when the cloud descended limiting visibility.
I met a couple folks at Shepherd Pass to ascend Tyndall with and met skier up there who climbed and skied Williamson and Tyndall that day- a very stout trip.
Definitively spring climbing conditions at the high passes and will be a bit before the melt out. Shepherd Pass photos
