I guided an ascent of Super Bock yesterday, Dec 14th. There is an extra crux mixed pitch to approach the Keyhole. This pitch is usually buried in avalanche debris, but not yet this year. Gear is hard to find as you top it out on climber's left (squirming by a large chockstone). I got a 3" cam lower down, a poor finger sized nut and decent knifeblade piton. A couple of stubbie ice screws could help.
The rest of the route is in challenging early season condition.
We walked across the Kicking Horse River from the chain-up area on the Trans-Canada.
Happy trails,
