In reply to GarethSL:
I would take the description from Farmer's Peak with a pinch of salt. It's a very minor peak visible from the camping at Point 72. I suspect it's easier than described and quite rambling. That's not to say it isn't a fun day out.
Some of our team walked up the east side of the Ketil Pyramid (the smaller peak on SW of Ketil. It was mostly walking, with some steeper sections over slabs.
We were rock climbing and didn't explore much in the way of ridges. The valley leading east from Point 72 was spectacular, but it didn't have obvious ridge mountaineering routes. Suikkasuaq to the south had a couple of I remember rightly. The peak you mention to the NW of Ulamertorsuaq has some rock climbs on the face, but I don't recall if the ridge has been climbed. Some of our team ventured into the coire behind it, which was a bit of a rock funnel.
