The sandstone “fins” in the Slickrock Member of the Entrada Sandstone (Middle Jurassic), east of Salt Valley.
North end of Salt Valley showing the plunging end of the collapsed salt-cored anticline structure. The primitive Salt Valley Road follows the spine of the structure towards the northwest, with strata dipping gently outward in opposite directions. Those are the Book Cliffs in the distance composed of the Cretaceous-age Mesa Verde Group. (Click on image to enlarge.)
Densely jointed terrain in the Moab Member of Curtis Formation (Middle Jurassic), west of the Salt Valley.
