The pdf ebooks on this site are definitely worth purchasing.
The rock art on this page was photographed to the west of Fillmore, UT. Specific sites include the Great Stone Face panel, the Devil's Kitchen site, Round Tank, and the Paxson Shearing Corral site. Internet sites generally attribute the rock art to the Great Basin Curvilinear Style, and the Fremont.
I actually camped at Devil's Kitchen and those photos were taken at sunset and sunrise. Paxson Shearing Corral is best photographed in the morning. I photographed the Great Stone Face panel in mid afternoon.
NOTE: in the book Petroglyphs and Pictographs of Utah: Volume Two by Kenneth B. Castleton, Paxson Shearing Corral is known as Paxton Corral (note the "t"). I'm not sure which is actually correct (Paxson or Paxton). Castleton believes the Paxson Corral to represent Desert Archaic with possible Fremont elements.
