Characteristic ruin, Pueblo San Juan, New Mexico. Photographer Timothy O'Sullivan is seated on right, next to his 10 × 12-inch large-plate camera. Photograph courtesy Library of Congress. This site is not the pueblo historically known as San Juan Pueblo (now Ohkay Owingeh). Rather, this site came to be known as Salmon Ruins or Pueblo, and is located on the San Juan River, just west of the town of Bloomfield, New Mexico.
