Another Chronometric Date Back

I just wanted to let you, the backers, know that I paid for another date from Guevavi Mission, and the result has just come back. This means that I now have dates for every adobe structure that could be a church in the Guevavi vicinity. This date places the main mission at 1790+/-40 suggesting that it is most likely a Franciscan mission, as I expected, rather than the 1751 Jesuit mission. (The lab says the central date, e.g., 1790 is highly likely and the standard deviation diminishes in likelihood as distance from the mean increases.) This means that the Franciscans likely built a new church after the expulsion of the Jesuits, as was generally the case in the Pimeria Alta. The building we plan to test this winter dates more closely to 1751 and is likely the last Jesuit church at Guevavi. Our tests will be focused on discerning whether the building we dig is a church or a house, for example, for the priest. Thanks again for your support.

    Butch Farabee remembers getting to Guevavi 60 years ago when the walls were much higher and the site was more remote. Of course, I had no idea what I was really looking at. Thanks Deni for helping me understand all of this.....

About This Project

Jornada Research Institute
Guevavi was a major focus of missionization efforts among the Sobaipuri-O'odham. We think we have identified the 1751 Jesuit mission among six adobe structures that surround the recognized NPS mission. I will date each with adobe wall samples using the luminescence technique. This will inform on which of these adobe structures date to (a) the Kino period (1691-1711), (b) 1751, (c) which are Franciscan, or (d) later mining/ranching features.
Blast off!
