Pretty sure T. pallidipennis is correct. The only other one in the region that looks the same is T. latifasciata, and the likelihood of that flying up high into the mountains is pretty much nill. Also, it is pretty rare in the region now (likes indisturbed alkali and silty flats on the plains best, and basically never gets up into the mountains).
It doesn't seem to be mentioned often in literature, but T. pallidipennis is migratory and moves around constantly. Adults can be long-lived (for perhaps up to a year as well), and they can produce multiple broods in a year (unusual among Trimerotropis). It can fly hundreds of miles north out of the southern deserts into Colorado, Utah, and even Idaho and Wyoming with warm southerly winds, sometimes even during the winter (though winter is rare). It commonly flies to lights in swarms in Nevada, Arizona, and New Mexico (and sometimes elsewhere), particularly in late winter and spring (depending some on where you are). I have found it flying around at the top of the San Juan Mountains on snowbanks above timberline on warm days in April and May, not just one or two, but sometimes a lot of them, and for sure these didn't breed and mature up there.
