Arroyo Hondo Pueblo
New Mexico, United States
Arroyo Hondo Pueblo was a pueblo in the upper Rio Grande valley, New Mexico. First occupied in the 13th century, the complex grew rapidly, and at its peak in the 14th century contained up to a thousand rooms; it has been called a "pueblo boomtown". However, it was short-lived, and the site was abandoned by about 1425. The pueblo has been the subject of a major archaeological research project since the 1970s, directed by Douglas W. Schwartz. It was listed in the United States National Register of Historic Places in 2007.
