Carrizo Badlands after a rainshower had passed through, from Canyon Sin Nombre, Anza Borrego Desert State Park, California. December 2014.
At the turnoff for Canyon Sin Nombre (dirt) road is a spot called “Badlands Overlook”. It’s probably the best viewing point along Highway S2 because it’s somewhat higher up, before the drop at Sweeney Pass, but don’t expect too much if you stop there. :)
