A Wylie Single Tent Interior, Yellowstone Park, circa 1910

Yellowstone National Park, established 1872, was America's first national park. During the first decade of the 1900s, tourists could take the park's Grand Tour by horse-drawn carriage, which involved stopping at a fancy hotel every night. Those who couldn't afford this option might choose the less expensive "Wylie Way," which involved lodging in canvas tents overnight.
