NOT A RECLUSE.
Sorry but this looks NOTHING like a recluse, try the site called ‘Spiderbytes Recluse or not’ for help, and read Rick Vetter’s articles, he’s regarded as one of the world’s experts on the brown recluse spider (and the misidentifcation of them).
Utah is reportedly on the very egde of the range of Loxosceles reclusa (their range is logged by recorded/documented finds by experts).
It’s unlikely you will find any there except for isolated colonies brought there through human transportation/shipping.
