“Spring Equinox Tour to Los Morteros and Picture Rocks Petroglyphs Archaeological Sites”

March 19 @ 8:00 am - 12:00 pm

TOUR FULL – WAITING LIST Old Pueblo Archaeology Center’s “Spring Equinox Tour to Los Morteros and Picture Rocks Petroglyphs Archaeological Sites” with archaeologist Allen Dart will be held on Tuesday, March 19, 2024, from 8:00 am to 12:00 noon. The tour group will meet at and depart from Silverbell Road and Linda Vista Blvd. in Marana, Arizona.

The 2024 vernal equinox occurs on Tuesday, March 19, 2024 at 8:06 pm Mountain Standard Time (Mar. 20, 3:06 am Greenwich Mean Time). To celebrate the equinox day (but not the exact time!) and explore ancient people’s recognition of equinoxes and other calendrical events, archaeologist Allen Dart (Old Pueblo Archaeology Center’s executive director) leads this tour to Los Morteros, an ancient village site that includes a Hohokam ballcourt, bedrock mortars, and other archaeological features; and to Picture Rocks, where ancient petroglyphs include a solstice and equinox calendar marker, dancing human-like figures, whimsical animals, and other rock symbols made mostly Hohokam Indians between 800 and 1100 CE. An equinox calendar petroglyph at the site exhibits a specific interaction with a ray of sunlight on the morning of each equinox regardless of the hour and minute of the actual celestial equinox, so participants in this tour will see that sunlight interaction with the calendar glyph unless clouds block the sunlight.
The request donation is $35 ($28 for Old Pueblo Archaeology Center and S’edav Va’aki Museum Foundation members) helps cover Old Pueblo’s tour expenses and supports its education programs about archaeology and traditional cultures.  Donations are due 10 days after reservation request or by 5 pm Sunday, March 17, whichever is earlier: 520-798-1201 or info@oldpueblo.org.
