Pretty sure that super wide buck in the 4th pic isn't from Utah...that sure looks like creosote in that pic, which grows in the Sonoran desert. None of the other pics have any big bushes in them. That sure looks like a sombrero rack to me too. Notice you also don't see any structures in that pic. I looked at the Utah poaching pics on MM...hard to say, but I don't think it's the same buck.
