Those are the Monitor and Merrimack buttes that are unmistakable when you approach Moab or drive up into the Island in the Sky. Named after the first iron clad civil war ships.
A few years ago someone had asked if there had ever been any images of them because no one ever posts them.

That was a 400mm lens at around 340mm.
