Posi-Ouinge, the 'Greenness Pueblo,' is a large prehistoric village dated to the 13th through the 16th centuries AD. The pueblo may have had well over 2,000 rooms, making it one of the largest in the southwest. The village was inhabited by Tewa Indians whose descendants now live near the Rio Grande in the Espanola area. The word 'Tewa' refers to a group of Puebloan inhabitants living along the northern Rio Grande and speaking a similar language. Today, the pueblo lies above the hot springs resort at Ojo Caliente. A short, self-guided hike beginning just west of the Mineral Spring Hotel takes you up onto the river terrace above and then around the site through room blocks and to vistas with beautiful views of the Ojo Caliente valley.

There is access to the trail from the Ojo Caliente Mineral Springs Resort, which is located in the small village of Ojo Caliente. Ojo Caliente is along Highway 285, about 25 miles north of Espanola, NM.
