On Saturday, March 11, 2023, from 11:00 a.m. to 1:00 p.m., head over to Mission Garden to hear “Archaeology Talks” by archaeologists Homer Thiel and Allen Denoyer. Homer and Allen have decades of experience between them in the archaeology of the Tucson Valley and the Santa Cruz River floodplain. Homer will speak about 4,100 Years of history along the Santa Cruz River, and Allen will relate some of the experiences of participating in the excavation right in Mission Garden. This program is sponsored by Friends of Tucson’s Birthplace with a $5 per person suggested donation. Mission Garden is located at 946 W. Mission Lane in Tucson.
