We made it to Trail Crest around 11:45, then stepped off around noon, made it to the summit at 3:30ish, made it back to the start of Trail Crest around 6. Yeah, I was also pleasantly surprised to see it melt that quickly!
Indeed, lesson learned, I'm definitely buying/making an ice axe leash before I ever need to use an ice axe again! Very important note!
Thanks!
