Chaco Canyon National Monument

For fourteen miles, both sides of a New Mexican canyon sixty-five miles equidistant from Farmington and Gallup are lined with the ruins of very large and prosperous colonies of prehistoric people. Most of the buildings were pueblos, many of them containing between fifty and a hundred rooms; one, known to-day as Pueblo Bonito, must have contained twelve hundred rooms.

These ruins lie in their original desolation; little excavation, and no restoration has yet been done. Chaco Canyon must have been the centre of a very large population. For miles in all directions, particularly westward, pueblos are grouped as suburbs group near cities of today.

It is not surprising that so populous a desert neighborhood required extensive systems of irrigation. One of these is so well preserved that little more than the repair of a dam would be necessary to make it again effective.
