Hello, guys I went up to the summit on Tuesday, June 28, going up the Chute like most other people. The interesting part is that on the summit I met two young guys who said they had come via the switchbacks. They didn't have any crampons or microspikes, only hiking boots. However, they also said they found snow in a few places and had to scramble up the rocks to avoid them. Those guys were young, athletic and experienced hikers.
Maybe someone who climbed the switchbacks could give first hand information, I haven't seen the switchbacks myself. The snow at Trail Camp and on the Chute is melting fast, so any trip report might become obsolete after a few days.
