Red Rock State Parks - there are three of them; one in New Mexico, one in Arizona; and, one in Utah. A real thrill hiking in these places.
The terrain here is by John Robertson (Schmeerlap). He had created a heightfield using GeoControl ; saved as a .ter and imported it into TG2 where he added some displacement and strata. Additionally, I added three populations of dry shrubs by Walli.
Enjoy...
