As part of a 7 Kane weekend bender and 5 Kane long weekend Monday. Whaleback - Isolated - McArthur - Pollinger - Kiwetinok - Kerr 17.5 hrs 2200m 41km. After Nigel and Wilcox on a casual Sunday I drove to Takkakaw Falls parking lot and shot the shit with Bert before bedding down in the back of the Subaru for rest of the feet (so much better than driving back to Calgary and back in the morning). Up at 4:15am and Rob, Babette, Kelly and I were on the trail at 5am by headlamp. Whaleback is sweet ridge and highly recommended. Isolated is indeed isolated and the glacier was more exciting than expected. First time for Babette and Kelly and we played around a bunch with crampons and then avoiding what were larger than expected holes and crevasses. Tried for a line of ice but turned around when it required a airborne jump. Alternative lower angle approach involved a few very large snow bridge crossings which made for a true mountaineering adventure. Isolated went down at noon for the first Kane of the day. Ascent up and over bergschrund of McArthur was straightforward and we could see the ridge line to Pollinger (a bump) and Kiwetinok which looked prominent. Approaching Kiwentinok looked more serious than it was. We didn't have the guidebook and so were wondering about the foreshortened view which looked steep and loose. Turned out to be not bad at all. On the summit at 5pm. Descended rapidly to the lake where the rain and driving wind came. Not wanting to have to hike up there again, I made a push for Kerr. It was more involved than I had hoped for the end of day rain. Sunshine broke briefly after I ascended a snow waterfall, steep mud slope and then around to the SW side to the summit. 7pm at summit with 40 min descent to trail and 8:30pm at Stanley Mitchell. At the car by 11pm. Home in Calgary by 1am. Knackered.
