What a sad way to start the morning - Ken is right about narrow margins. I was on Baldy a couple months ago, in great conditions, and almost took an odd step off the trail which would have sent me down a VERY steep and long grade to who-knows-what below. It's really important towards the end of your climb to be mindful of your motion, tired muscles often lead to tripping or small errors, which on a mountain, can lead to your death. Poor lady, I hope she didn't suffer.
