Bee,

If you can do that short but narrow section of the ridge as you are about at the summit of Cloud's Rest (coming from the east, that is), then you should have no problem with any of the windows on the Main Trail of Whitney. I've done both. I actually was more cautious on that small section of Cloud's Rest than I ever was anywhere on Whitney (summer hiking conditions assumed).

If future generations are to remember us with gratitude rather than contempt, we must leave them more than the miracle of technology. We must leave them a glimpse of the world as it was in the beginning, not just after we got through with it.
