Very simialr to the version in adams book "The print" but cloud formations are a little different and dodging/burning are different in the sky. The position of camera looks to be identical though so its quite possible he made several negatives whilst clouds moved. Whether it was printed by him is another matter. I don't think anyone could say unless they knew the source of that actual print.
It's probably poor reproduction, Ansel Adams didn't like warm tone papers.
Adams printing varied quite a lot over the years so some images do have quite a different feel depending on which periods the actual prints were made. At one point his prints were much more contrasty with heavier dodging and burning, I was quite shocked at the marked difference in quality of work in one exhibition (Oxford 2008) which came from his daughters collection. I'd seen all the images before in a major Ansel Adams exhibition but the prints there had far greater clarity and tonality.
Fly in to the airport at Jackson Hole, Wyoming. Leave the airport and just north of the airport there is a park. Head to the north end of the parking lot. Park car. Take care not to trip in the many tripod holes at that location.
