Three images taken in August, 1899 at Hopi Snake Dance ceremonies in Arizona by the Pennsylvania-born photographer Horace Poley, who traveled in the summers to observe and photograph Puebloan people, printing the photographs at his Colorado Springs studio. We find one of these photographs at the Denver Public Library, which identifies the location and date, and the other two are clearly from the same ceremony due to the presence in the images of the distinctive rock formation, upon which sit onlookers to the ceremony. Poley’s images are relatively uncommon in the trade and this depiction of Hopi ceremonies is relatively early for Euro-American photographers in the area. Despite the advertisements for the Union Pacific, Denver and Gulf Railway Co. on the verso, these photographs were not taken on its route.
