In reply to JackArn:
Just a heads up that the Grand Wall route (and general area, including many of the base cragging routes & bouldering) are currently closed and have been since late last summer, after a large chunk of the wall fell off. The Grand Wall route itself is unaffected by the rockfall, aside from some scarring on Mercy Me, but currently off limits.
I live in Squamish and don't know of any timeline to reopen. Fingers crossed it's this summer.
