About the Carter Mustang Herd

Join our email list to stay up to date ->

     The unique wild horses known as the Carter Reservoir Mustangs are located in a very isolated area, best viewed by horseback with local guides. They are considered a California wild horse herd as they are managed by the Bureau Of Land Management in Cedarville, California. 


     The Carter Reservoir wild horses 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. 


     The Carter Reservoir mustangs are not easy to view as their coloring can cause them to blend into the landscape. The herd roams in a remote desolate area in the high desert of northeastern California and northwestern Nevada, where sagebrush, juniper trees, lava rock rimrocks, hills, valleys, and canyons are plentiful.


     Great caution should be taken when traveling into this remote region located east of Cedarville, California. A high clearance vehicle is recommended if driving off of Hwy 8A. When traveling in this remote desert area, please tell someone where you are going and when you expect to return. Carry extra water. Have a full tank of gas. Cell phones may not have reception. Do not approach a herd nor get to close. Help keep them wild by staying a respectful distance. Use geldings if riding, stallions are sensitive to mares in heat and may try to take them into their herds. Do not get between a mare and her foal.  


     Coyotes, fox, antelope, deer, elk, mountain lions, bobcats, an occasional bear, raptors and other birds are seen among wild horses in North America. In the steeper, rocky terrain in Carter Country, there may be rattlesnakes. Where the Carter Reservoir Mustangs roam you are more likely to see antelope, deer, coyotes and lots of raptors. There are a few mountain lions in the area, but it would be very unlikely to see one.  


      Watch these amazing creatures roam wild as they've done for more than 600 years.
