Brent N, I found the writeup accompanying the video here:

Yosemite YEBlog @ yexplore.com

From the blog:
Quote:
The trail was virtually free of snow and ice. Rarely is the Mist Trail so dry, and there were literally a small handful of patches of snow that were easily avoidable as you made your way from Little Yosemite Valley to the summit. Sub Dome was bone dry and the cables were free of any moisture.


By the way, if you visit that blog, he has some incredible Vernal Fall ice pictures near the bottom.
