With flashing eyes and thundering hooves a newly-escaped mare, a rancher’s rope still hanging from her neck, joins a swift moving herd racing across an open valley. Mustangs are a mythic symbol of freedom, heroism, romance, limitless possibilities and the vanishing West where it was estimated that two million wild horses roamed the largely unfenced American West in the early 1900s. Some of those mustang herds descend directly from horses brought over by Spanish Conquistadors in the late fifteenth century. Other herds’ ancestors escaped or were let loose by settlers, ranchers or Native Americans. - BM
