We've climbed seracs at Baker a number of times to prepare for the North Ridge, but nothing over more than a rope length (with anchors). We worked the lower glacier east of the bluff along Glacier View. Can you get better climbs by dropping entirely to the bottom of the Coleman Glacier? This would mean heading down the trail (from camp in trees), left at the moraine and dropping all the way to the bottom. In the past we've gone left from where the trail breaks on to the moraine, down about 200 m, and working those faces, but you only get about one rope length. There's still a lot of ice below that point - better climbing lower? Thanks.
