“Tour of the Desert Laboratory on Tumamoc Hill and the Laboratory of Tree-Ring Research”

July 13 @ 7:45 am - 12:30 pm

On Saturday, July 13, 2024, join Old Pueblo Archaeology Center’s “Tour of the Desert Laboratory on Tumamoc Hill and the Laboratory of Tree-Ring Research.” The tour group will meet at 7:45 a.m. in the courtyard at Mercado San Agustín, 100 S. Avenida del Convento, Tucson, AZ. The tour will end back at this same location around 12:30 p.m.

This Old Pueblo Archaeology Center summer tour visits two TOO-COOL environmental-science laboratories in Tucson – the Desert Laboratory on Tumamoc Hill and the Laboratory of Tree-Ring Research (LTRR), both administered by The University of Arizona (UA). The Tumamoc Desert Laboratory began its existence in 1903 as the Carnegie Desert Botanical Laboratory established by the Carnegie Institution of Washington and is now listed in the National Register of Historic Places. The Tree-Ring Lab also has a venerable record of research in archaeology, astronomy, and environmental sciences, created in 1937 by the founder of dendrochronology as a science: UA Professor of Astronomy Andrew Ellicott Douglass. Tour presenters and guides will include archaeologists Paul and Suzanne Fish, the Tumamoc Lab’s Robert Villa and Lynne Schepartz, and LTRR docent Donna MacEachern. The drive from the Mercado San Agustín meeting place to the Tumamoc Lab is limited to five vehicles so tour is limited to 20 people and carpooling is required. After returning to the Mercado, all participants can take their own vehicles in a caravan to the LTRR.

There is a $35 requested donation ($28 for Old Pueblo Archaeology Center and S’edav Va’aki Museum Foundation members) supports Old Pueblo’s education programs about archaeology and traditional cultures. Donation prepayments are required 10 days after reservation request or by 5 pm Wednesday July 10, whichever is earlier: 520-798-1201 or info@oldpueblo.org
