Basically big empty field with electrical hookups for event camping; pulled in late on a non-event evening, had to drive around a bit to find camping area, set up tent, nearby RV owner pulled in late in the early morning, grassy area, no bathrooms, back on the highway in the morning.
All of the campgrounds on UT 128 were full during our late night drive way out that direction; easy enough to find Behind the Rocks, pulled in late, found an open spot, still some people up at early morning hour, sandy dirt spot, rough road into area, woken early by atv users, drove into town for bathroom and breakfast.
