Photograph by Charles A. and Anne Morrow Lindbergh, 1929. Pueblo del Arroyo lies immediately next to Chaco Wash, and its location inspired its name. When the Lindberghs photographed the site, the circular tri-walled structure on the western extension of the pueblo was being eroded by the wash. Neil Judd excavated a large part of the pueblo in the late 1920s, resulting in the empty rooms visible in both photos. The more modern buildings to the southeast of the ancient pueblo were built by Richard Wetherill in 1899 and served as a boarding house for archaeologists and other visitors. They were converted into the Chaco Canyon Trading Post in the 1930s. The road to Gallup crossed the wash nearby.
