I do not disagree actually, but the colourcast at the time was extraordinarily strange, And I wondered why at the time. The sun was shining on the prairie / plains and a bit on ( I think a suburb to Salt Lake city ) while the backdrop mountains were in shades but still at a very cool temperature. At least that's the explanation I received. This is quite high above sea level, approximately 1300 meters. Mountain tops are much, much higher. It was like a mirage as the prairie was very hot in late august / early september.
