Given the conditions, I like the second photo the best. To answer your question from my opinion/experience only, I shoot to fill my frame with subject, (which is why I liked #2) as the sky blends in otherwise and doesn't add to the image. Happily, Yosemite has a lot of opportunities for this (I love shooting there in winter too)
I love all of them, this is one of the rare situations where I like the blown out sky, it adds to the starkness of the photo and gives good contrast with the dirty detailed ground... great shots!
