The first Mogollon branch defined was the Mimbres. Here, sites have been excavated in the southern part of the Mimbres drainage and in the adjacent part of the Gila drainage.

Harris Village (Haury 1936b) is located about a quarter of a mile east of the Mimbres, New Mexico post office, on a large, flat terrace which rises abruptly some 20 m. above the east bank of the Mimbres River. It is about 1,850 m. above sea level. The village occupied several acres, part of which was not explored. Easily approached from all sides, defense does not seem to have been a factor in selecting the village site. The surrounding countryside is rugged and hilly, but agricultural land is available in small fields along the stream. The area is in the lower part of the pinyon-juniper belt, and a few trees occur on the site. Cottonwood, poplar, and walnut grow along the valley.
