The true summit is at the top of the sheer cliffs at far right, an easy walk on the other (south) side.
This north summit, much more challenging, is a thin flake with sheer drops on either side. We got to within 5' of the top, with Gwynnie belayed in a safety harness. This was rather technical dogwalking; Class 3 means "frequent use of both hands, but rope not required". We were not really very exposed, but there were 100' drops on either side, and we were taking it very seriously.
Just to get here, we had to drop down some dangerously steep snow, backing down with an ice ax and the dog on belay. Like humans, corgis can easily climb up stuff they cannot climb down, so this snow descent was a challenge. I've learned that if you belay a dog on steep snow, the rope must be kept very short, lest it wrap around a leg or something and hurt them if they fall -- and they do fall, but holding a small dog sliding on snow is not difficult.
Gwynnie is 10 years old. This was an 11 hr. day (with lots of loafing time). The surrounding scenery is jawdropping.
