James A. Mason, Ph.D., P.E. (National Park Service) will give a presentation reviewing the construction means and methods history of the Spruce Tree House Alcove Complex and the subsequent work of repairing and stabilizing the expansive site, with a focus on reinforcing the Alcove Arch. Presentation topics will include Ancient Puebloans' construction means and methods, damage inflicted to the dwellings by artifact trophy hunters, repairs and stabilization methods from Fewkes and Nusbaum to Lancaster, the 1960s arch stabilization work, and current analyses and potential stabilization methods of the Alcove Arch.

The Brown Bag talks are held in the OAS conference room at the Center for New Mexico Archaeology. Talks are informal (and you can bring your bag lunch). Usually, seating is adequate, but we have had 80-plus people show up for a talk in a room that can only hold 35. Seating is available on a first-come-first-served basis. Admission is free.

The Center for New Mexico Archaeology (7 Old Cochiti Road) is located off of Caja del Rio Road, across from Challenge New Mexico on the way to the Santa Fe Municipal Golf Course. Take 599 to South Meadows Road, continue through the traffic circle west along the Frontage Road to Caja del Rio Road. CNMA is on the left-hand side of the road and is the large building with white sail-like skylights on the roof.
