What is the crevasse risk on Gannett glaciers? I know the glaciers in that area such as Dinwoody and Gooseneck aren't massive and aren't making dramatic turns and dips which causes greater fissures to develop. Is the primary obstacle the snow bridge crossing the bergshrund for the Gooseneck couloir route? I'm planning a trip in July and am weighing how many people to take, gear, logistics, and overall skillset of the people going. From what I've seen, most crevasses there are fairly narrow and identifiable, but I don't want to take a casual approach to it.
Thanks!
