We were therre last year. It's the Lloyd-Cleveland Dig, somewhere in the middleof nowhere and south of Price as was said. However, they do not dig every day. We lucked out and there was a group of about six, there in the shelter of a quite large metal building, with no floor. There was a hole about 4-5 deep in places with bones sticking out of the muck and the students very carefully cleanng around them to dig them out, catalogueing and whatever else they do. We were not allowed inside, but could only watch from an open door. Being it was June and the sun was pretty warm, we didn't stay around long. But it was a good trip out there and there is a small museum and the student intern was quite informed. Bring water and food, as nothing is available there. There is a walking trial around the area, where lots more bones are buried.
Enjoy, Daisy
