I sort of knew what I was searching for and sort of didn’t. After rowing around a bend in the Green River, Rock House Canyon opened dramatically ahead. I tied my raft to shore and walked up a dry creek bed. Above rose buttes and fins of orange-brown rock, part of the Green River Formation. This geologic unit is comprised of crumbly shales and sandstones which were deposited millions of years ago when the region was flooded by the long-gone Lake Uinta.
The cliff faces shone brightly in the morning sun of early August. Somewhere near here was a Fremont Culture petroglyph panel—but I didn’t have any specifics about size, subject matter, or precise location. Also, based on the fresh claw prints in the beachside mud, there might be a nearby bear who shared my interest in rock art and amateur archaeology.
