Brian,
All of these photos are absolutely stunning! It makes me want to get on a plane asap to Yosemite. I was there about 25 years ago...........and don't remember it being this awesome.

Between 3 & 4 I think #3.....or maybe #4. I can't decide. They're both great composition and excellent color/contrast. The reflections are beautiful. I love the mountains......and everything else as a matter of fact. Thank you so much for sharing.

Liz
