Some great images. Love 1,2, & 3. Picture 4 is a super panorama but you need to straighten out the tilt issue. !! Unfortunately 5 with the black trees seems to have missed the mark. Same for 7 that seems under exposed. Both images would have greatly benefited from either the use of a graduated ND filter or HDR imagery. You bounced right back with that old rusty car, and the final B&W is spot on. As a side note, all the color pictures viewed on my monitor, the snow seems to have a some what bluish tint, but I just can't be sure.
Enjoy your vacation, it seem like you're in photographer's heaven.
RV place south of Yosemite? Oakhurst? I usually camp at Bass Lake and ride the motorcycle through the park. It's worth the hike if you can do it. I've never done it myself but if you look at my flickr in the travels folder you can see my amateurish shots from Glacier Point, it's an over-whelming majestic view.
