I like it Jim, What's the speculation on the age of the culture that made these petroglyphs. Current thought is that these could be up to 15K But, while unrelated, there are some similar to this in French caves that are ~ 35,000 years old. Then again, the horse was supposed to be reintroduced into the Americas with the Spanish after going extinct 80K ago on this continent.
Very generally speaking, Reuss, I'd 'speculated' that these particular horse figures were produced by a person of the Ute culture because that is the culture who lived --and still live-- in the area where these figures were made. Other peoples --earlier cultures-- lived here previous to the Ute people's 'arrival' (which I and others 'speculate' began, gradually, in the 1200-1300's), but during those times, neither those earlier cultures nor the Ute had or even knew of the horse, and that remained the case
in this area until around 1650 or thereabouts. You're aware that there had been a species of horse that had gone extinct in N. America; you're also aware (?) of some "current thought" that some rock art (in the Americas) could date as far back as (a Pre-Clovis period of) 15,000 b.c., but those sites are
not in this immediate region. Paleo sites of that very early age --Pre-Clovis-- have been documented in NV, Virginia, Texas, &etc., and likewise in S. America in Brazil's Nordeste and at Chile's Monte Verde site; even scientists and researchers who knew the well-known Paleo 'cave painting' sites in Europe (Lascaux, Alta Mira, etc.) were somewhat blown away by the discovery of the art in Chauvet Cave (35,000 b.c.) because it predated what they knew by several thousand years. And then there's a site in Indonesia that's been tested/dated as being older still.
Culture is, in large part, defined by the technologies a people have. Even the Utes had to have undergone a cultural shift of sorts with the acquisition of the horse, though what those adaptions would've been would be a subject for someone better versed in Ute culture than me. What is known, however, is that linguistically, Ute speakers are part of a long line of Uto-Aztecan language groups. They're linguistically 'related' to people who migrated up --prehistorically, obviously-- from Meso America, through the deserts of western California and central Nevada. That language group is entirely different from the Athabaskan language groups (the Navajo, the Apache, &etc) who migrated down through America's Great Plains, generally west of the Rockies. And both those language groups are distinctly different than the Kersean (and similar) linguistic groups of the people --the Hopi, the Zuni, the Pueblo tribes generally-- who were already in place before the arrival of the Utes or the Navajo (etc), and were most closely related to the so-called 'Anasazi' or 'Fremont' cultures.
