From the Chimney Peak Fire Tower overlook you can see across the entire Alabama Valley and Ridge. The ridges on the horizon contain Cambrian through Pennsylvanian strata and represent a basin that was actively receiving sediment until the early part of the Alleghanian orogeny. The rocks along Choccolocco Mountain were uplifted at least ~50 million years earlier and may represent a previously unrecognized fold and thrust belt that began in the late Devonian.
