===Cosmology and astronomy===
The Chumash cosmology is also centered around astronomy. Rock art and arborglyphs that have been found within Chumash sites are thought to have depicted Polaris (the North Star) and Ursa Major (the Big Dipper). Specialists Rex Saint-Onge, John R. Johnson, and Joseph R. Talaugon argues in their article ''Archaeoastronomical Implications of a Northern Chumash Arborglyph'' that these two astrological entities were paramount to the Chumash belief system as well as their perception of time. It is believed that the Chumash used these constellations to determine what time of the year it was depending on the position of Ursa Major around Polaris.<ref name=":1" />
