Native Americans, including the Methow people, were the first inhabitants of Winthrop, with evidence of human habitation at least 8,000 to 10,000 years before present. They lived along the banks of the Methow and Chewuch rivers, where they harvested camas root and berries, fished, and hunted. The Methow had seasonal camps and returned annually to the upper valley in the summer once they acquired horses in the 18th century. The Columbia Plateau peoples, including the Methow and Syilx, established routes over Cascade Pass to trade with Coast Salish tribes in modern-day Skagit Valley. The population of the Methow people and other Columbia Plateau tribes were devastated by smallpox epidemics by the 19th century. The tribes under the leadership of Chief Moses were assigned by the federal government to the Columbia Reservation in 1879, which included the Methow Valley.
