Traverse from Challenger Date Climbed: Aug 2, 2014
It was in the way of my return via Whatcom Pass, so it had to be done. It's worth it for the amazing view of Challenger, but should really be climbed in the other direction. The north ridge from Whatcom Pass is a chossy nightmare that sucks to descend. The cable car over the Chilliwack was a real trip, though. Trip report.
Whatcom Peak via Perfect Pass Date Climbed: Aug 20, 2007
After an attempt on Challenger Norman and I left Perfect Pass and ascended steep snow and good rocky ridge to Whatcom Peak. Down crumbly north side and out to Chilliwack river and Hannegan Pass. The cable car river crossing is pretty cool.
