Presidio San Agustín del Tucson Museum will be sponsoring the “Santa Cruz River History Tour” on July, 21, August 18, and September 15, 2023, which starts and ends at Mission Garden, 946 W. Mission Lane, Tucson. Each tour will be from 8:00 to 10:00 a.m. The $30 tour fee ($25 for Presidio Museum members) includes admission to Mission Garden. This two-mile walking tour led by Mauro Trejo focuses on our relationship with the Santa Cruz River, how it supported Tucson’s early residents, and the factors in the 19th and 20th century that affected its demise. The tour begins and ends at Tucson’s Mission Gardens and includes the sites of the former Spanish mission and the O’odham village that was the origin of modern Tucson. Attendees will also visit Tucson’s tallest tree and the Garden of Gethsemane, a holy site of statues made by WWI veteran and artist Felix Lucero in the 1940s.
