Is it easier/safer to ascend the Chute before the sunrise (3am) while it is icy or it is best to do so when the snow soften up in early morning (7am)? We will be using ice axe and crampons. Also, any last updates on the switchbacks? The conditions change daily in this time of the year so I thought to check for one last time before summiting on Monday. I’d really appreciate your help.
