Thanks for the comments. Tough for me to pick favorites since they're mine.
I didn't really have any expectations, but I sort of felt that #4 would be the one most found attractive.
On the day of #4, I spent the late afternoon and evening driving west from the east end of the park. That cloud formation dominated its portion of the sky during that time, and I have several images that include it. It was interesting to watch how it changed.
