Montezuma Well, about 11 mi. n.e., is a detached portion of the monument. The limestone sinkhole, 470 feet wide and more than 55 feet deep, is rimmed by pueblos and cliff dwellings. A source of water to the fields of ancient peoples, some of the ditches dug A.D. 1200-1300 are still visible. A self-guiding trail is available (not recommended for wheelchairs).
Picnicking is permitted.
