Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.
Expansive eroded badlands of clay hills, mudstone, and fossil-bearing sediments on the Imperial / Anza-Borrego desert margin east of the Coyote Mountains. A classic Colorado Desert badland landscape for geology touring and photography, accessed from desert tracks near Carrizo Mountain / Split Mountain country rather than the coastal Anza-Borrego visitor hubs.
