The unique Spanish horses known as the Carter Reservoir Wild Horse Herd are located in a very isolated area, best viewed by horseback with local guides, Riders of the Sage. The herd has been genetically tested and shown to be of direct Spanish descent.

"The Carter herd is likely derived in part from North American stock, but the herd does have an Old Spanish heritage component that is quite rare and is not through North American breeds," states Dr. Gus Cothran, Clinical Professor of Veterinary Integrative Bio Science, College of Veterinary Medicine at Texas A&M. Scientifically, the Carter herd represents descendants of the Spanish Barb horses which appeared in the 1600s.

The Carter Reservoir wild horses also exhibit physical color characteristics known as the "dun factor," which was also common to a major portion of the horses which the Spaniards reintroduced into North America in the 1600s. Color classification of the dun factor are: dun, red dun, grulla ( mouse gray),  buckskin, claybank and variations of these colors. Markings on horses having the dun include dorsal stripes, herringbone strips, zebra stripes on knees and hocks, chest, rib, and arm bands, outlined ears, top 1/3 of the ear on its backside darker than body color, fawn color inside of ears, multicolored mane and tail, cob webbing on face and face masks. An individual having the dun factor may have many, but not all of these markings.

The Carter Reservoir mustangs are not easy to spot as their coloring can cause them to blend into the landscape. The herd roams in a remote desolate area in the high desert, where sagebrush, juniper trees, lava rock rim rocks, hills, valleys and canyons are plentiful. Great caution should be taken when traveling into this remote region located near Cedarville, California. Coyotes, antelope, deer, elk, mountain lions, bob cats and birds are most commonly seen along with the wild horses. Horseback is recommended.
