That certainly sounds like
A reasonable place to find P. marginalis.

Moved from Whites and Yellows.

Moved from ID Request.

Id be inclined to agree
that it's a very unmarked individual of Pieris marginalis. Especially likely if you were up in the hills, as apposed to down low (a little more exacting location is helpful, since Iron County is large and varied).

 
Location
I was by a cabin on Kanarra Mountain near Cedar City

maybe Subfamily Coliadinae - Sulphurs and Yellows
Or not.. :) Just an idea. I'm definitely not good with the butterflies. Mainly wanted to say that's a nice shot.

 
I'd say Pierinae
The Whites, close cousins to the Coliadinae - yellows are, well, yellower, and the pale female forms are usually spotted, not like this almost unmarked individual.

I don't know anything about Utahn butterflies, but I'd ask someone who did to take a look at the Margined White, Pieris marginalis:
