As leaders of the nascent United States signed the Declaration of Independence, in this region 250 years ago — then arguably a claim of Spain — another revolution was afoot, on four feet. Although present in this area thousands of years ago according to fossil evidence, the horse had disappeared from western North America until Hernan Cortes made landfall much farther south, unloading more than a dozen horses in the Yucatan in 1519 from the holds of his ships. Indigenous peoples didn’t have to have horse technology explained to them. They ran with it, and the horse population spread like wildfire along the mountainous spine of the American West, so quickly that the area to become Northwest Montana saw horses decades before California. Some Indigenous people called horses “elk dogs” on first encounter. Horses were a dream come true: collapsing distances to hunting grounds and enabling easier travel across rugged landscape. They were integral to increasing trade, protection, and conquest. In little more than a lifetime, the Ksanka (Kootenai), Selis (Salish), Qlispe (Pend d’Oreille), and Niitsitapi (Blackfeet) saw horses transform life in the northern Rockies.
