The rarest of America's historical horse population, these horses can trace their documented roots back at least 100 years. Native American tradition, historical records and letters of old mustangers have helped the Windcross Conservancy begin to piece together the history of these horses. Some hail from deep into what is now Oklahoma, but was once the home of the traditional Osage people and their horses. Others come from way down in old Mexico, from the time of estancias, missions and pueblos. Diaries of conquistadors, letters of Spanish soldiers to home, legends and maps of the Old West are all used. With the addition of modern scientific genetic research we are just beginning to see path taken by these horses through history to today.
