According to Western Digs , the solar calendar has been marking the seasons for more than 700 years with a shadow dagger that travels across the sandstone face. This feature is made by a natural outcropping of rock above a panel of petroglyphs. Western Digs reports that the “shadow dagger” bisects a spiral carved onto the cliff wall, while another shadow interacts with a set of eight circles pecked into the panel’s left side.”

The researchers discovered the petroglyphs in the back country of the Wupatki National Monument site northeast of Flagstaff, in Arizona, USA. The area includes the ruins of dozens of sites built by Ancestral Puebloans, also known as the Kayenta or the Sinagua.
The Puebloans were an ancient Native American culture, who lived in southeastern Utah, northeastern Arizona, northwestern New Mexico, and southwestern Colorado. Researchers says that they developed as a part of the Oshara Tradition (circa 5,440 BC - 460 AD), which grew from the Paleo-Indian Picosa culture. Ancestral Puebloans lived in a range of structures from small family pit houses to larger buildings like grand pueblos - cliff side dwellings for defense and house clans. They especially dominated the Colorado Plateau and connected hundreds of communities around them.
