of the Onion Creek salt-cored anticline in this mini-pan view toward the west (click to enlarge). The highly-deformed gypsum caprock of the Pennsylvanian Paradox Formation is the light green to gray unit in the bottom of the valley, with the overlying red beds of the Cutler Formation (Early Permian) dipping off slightly to the north (right) and south (left). Those are the Fisher Towers on the skyline to the right of center.
