Major rockfall on Zodiac Wall

[glassgowkiss]

Seems like there is news about a major rock fall around Alaska Highway- Calling area. Apparently about 100x150ft section near the top collapsed, taking out entire slope below, from Northern Gully (trail to Angels Crest was apparently obliterated) to the east. Hundreds of trees are just smashed, pretty much opened the slope below the wall.

Most likely it would be a wise idea not to venture into this part, as more rockfall is a possibility in such situations.

So there are some new bouldering routes on the ground now?

New climbing routes as well, if the wall reopens. For now there is a huge chance of more major rockfall, as the impact of 1000 cubic meters of granite crashing onto more rock, most likely destabilized other large flakes. Looks like Yukon Gold had also major collapse (a few minutes before the main collapse), whole "Chilkoot Pass" exit is no longer there, 10b (second to last pitch of The Calling is partly gone, and upper part of 12a pitch is covered in debris. Most likely bolts on that pitch have to be replaced.

Wonder if it was related to the first really warm weather of the year? Also via another photo noticed that the chunk of rock that peeled off was topped by a tree covered ledge, I wonder if those root systems worked there way down creating some wedging? I have seen this in a few places at Index, in particular some of the upper sections of the country.
