On Saturday, Dec. 13, 12:30 – 2 pm, John Ninnemann, PhD, will provide a free presentation in the Vista Grande Public Library's meeting room about his upcoming photography exhibit at the library, “Archaeoastronomy: Sky Watchers of the Ancient Southwest.”

Ninnemann will discuss how these images provide a window into the sophisticated culture of the Ancestral Puebloans who once lived on the Colorado Plateau. It’s clear that the people tracked time, creating calendars based on sunrise/moonrise movement of the sun and moon in relation to both natural and human-caused features on the landscape. This knowledge was essential for agriculture as well as for guiding architectural orientation and ceremony. The exhibit documents sky-watching locations in Mesa Verde National Park, Chaco Culture NHP, Chimney Rock, and Yucca House National Monuments.

Vista Grande Public Library is a 501(c)(3) organization serving Southeastern Santa Fe County and is located at 14 Avenida Torreon, Santa Fe (in Eldorado).
