The Four Mile wild horses are known to be of excellent size with good conformation and color. This is the result of the influence of released Thoroughbred and Quarter Horse studs to the herds periodically up to 1978. It is also suspected that horses bred for Cavalry Re-Mounts may have also influenced the herd. In addition to the typical colors of bay, brown, and black, the wild horses include many chestnuts, pintos, paints, roans, grays, duns, grullos, and a few Appaloosas. Population 111.
