Heard from a PR past Monday that the switchbacks are open already. But she still recommended taking the Chute.
Yesterday, I heard (will try to post the FB link once I get it) the warm weather today and tomorrow should pretty much clear the switchbacks of snow.
We are planning on using them on Jun 17th (this Sunday).
Spoke to a PR again and as of today they are still recommending the Chute with crampons and ice axe. She claims the cabled section of the switchbacks still has snow and no traffic through it yet for any hiking path.
