This area, which lies a few meters north of the Mexican boundary, is covered by a creosote bush scrub, with Larrea tridentata the dominant. There is an exceptionally fine stand of the rare buckwheat, Eriogonum deserticola.  The uncommon holly-leaved burbush, Ambrosia ilicifolia, occurs here also.

Animals are typical of the west mesa region.  The Colorado Desert fringe-toed lizard, Uma notata, and the desert iguana, Dipsosaurus dorsalis, are found here as may the uncommon flat-tailed horned lizard, Phrynosoma m'calli, and the rare little desert pocket mouse, Perognathus longimembris arenicola.

There is a wash with an intermittent stream.

Much of the area is composed of heavily dissected Pliocene nonmarine sedimentaries.

Integrity:  The area is relatively undisturbed. 

Use:  Research, educational, observational.
