Northern Sonora: Cerro de Trincheras, La Playa, and Magdalena

February 8, 2020 @ 8:00 am - February 9, 2020 @ 8:00 pm MST (Arizona)


On February 8 and 9, 2020, AAHS is offering a unique opportunity to visit and learn about the entire cultural sequence of human occupation in northern Sonora, from Paleoindian to Padre Kino.  Making our way across the international border we will visit the mission of San Ignacio before exploring the central plaza in Magdalena de Kino and see the final resting place of Father Eusebio Kino.  After spending a peaceful night in Magdalena, we will visit the archaeological landscape of La Playa, which contains several thousand years of human use beginning around 13,000 years ago and including one of the largest the Early Agricultural period village sites in the region.  We will follow this with a carne asada lunch in Trincheras and stop at the museum and tour the type site for the Trincheras culture, the Cerro de Trincheras before heading back across the border for Tucson.

Dr. James Watson, Associate Director of the Arizona State Museum, has worked extensively in northern Sonora and will share his insights into human adaptations and cultural developments over the past several millennia in this part of the Sonoran Desert.

The trip will be limited to a maximum of 30 participants (a minimum of 20 participants are required to facilitate the trip) who will travel together by motor coach with an experienced driver.  The group will leave Tucson on Saturday, February 8th at 8 am and return in the early evening of Sunday, February 9th.   We will stay overnight at a hotel in Magdalena with an opportunity to explore this wonderful Sonoran town.  The participants will share the total cost of transportation, which will range from $100 to $120 per person depending on the final size of the group.  The exact amount will be determined in early January and sent out with payment directions.  Hotel and food will be the responsibility of participants, however AAHS will recommend a hotel and arrange for a block of rooms to be held.  

There will be some moderate hiking involved and the site is not wheel chair accessible.  Valid passports are required to enter Mexico however a SENTRI or Global Access card can also be used to return to the US at the Nogales Port of Entry.

We will need a commitment to join us by December 31, 2019 and then payment for motor coach transportation by January 15, 2020.  

Please respond to Chris Sugnet by December 31 if you want to come with us.
