Abo State Monument. Ruins left by former tompiros division of the Pito Indians, on Arroyo Empedradillo. First mentioned in 1598 by Juan de Onate. Became seat of Mission of San Gregorio, founded 1629 by Fray Francisco de Acevedo, who erected a large church and monastery, the walls of which are still standing. Abo is shown on L'Atlas Cirieux (1700).

Population during early mission days was probably two thousand. Prior to the Pueblo Rebellion of 1680, the village was abandoned because of Apache raids. The ruins have been excavated by the Museum of New Mexico and were declared a state monument on August 30, 1939. Abo is said to have been dedicated to San Gregorio, patron saint of the old city of Abo, Finland, but the name is a Piro Indian word used for the pueblo in 1598, whereas the mission was not established until thirty years afterward.

The chanting of voices and the ringing of the mission bell once echoed through this hushed valley. For over five hundred years, beginning in the early twelfth century, Tompiro speaking Pueblo Indians prospered here.

Reported Phenomena

The Investigation

We arrived just before sundown and swept the area for unusual EM fields.

After our third pass through the ruins a DC EM field of 4 milligauss was found near the main tower that appeared to be moving in a northerly direction. The field was followed for two minutes before we lost it and was unable to reacquire it.

We then shifted our attention to the surrounding areas. Another odd EM field ( 3.5 milligauss) was located 100 feet away from the main structure near the entry road. A photograph taken just after the measurement of the reading reveled an unusual mist like structure in the image.

We searched through the ruins again and found nothing of interest.

The ghost hunt was concluded at 7:30pm.

Initial Conclusions

Only one unusual picture was taken at the ruins.

A strange mist is in the photo just to the right of center. We have ruled out smoke and breath as causes and the "mist" is still a mystery.
