Barbier, Griffin Fox, Itzamara Ixta, Gina Mosqueda-Lucas, Brianna Rotella, Lindsey Willoughby Mission La Purísima Concepción was home to a vibrant Chumash community known as 'Amuwu that became reinterpreted and trans- formed as part of Spanish and Mexican colonialism. A UCSB archaeo- logical feld school set out to examine Chumash material culture in the rancheria that existed between AD 1813-1848. A series of 1 x .5 meter units were placed across a large midden deposit associated with the village to assess its extent and depth. Three other units, measuring 1.5 x 2 meters, were situated adjacent to one another in one room in an adobe building that housed Chumash residents. The most prominent archaeological discoveries yielded foodway patterns and evidence for trade and exchange, as seen through the identifcation of marine invertebrate and vertebrate taxa and glass and shell beads. The study of these materials highlights how mission laborers sustained traditional practices and simultaneously incorporated new ways of living into their daily routines, constructing their own histories and producing a new collectively founded identity. Diet and Subsistence Marine and terrestrial fauna made up a signifcant portion of the mate- rials excavated from the midden deposit associated with the Chumash village of 'Amuwu. The study of the zooarchaeological assemblages tells us more than simply dietary patterns. The fndings lead to further questions about where foodstuffs were acquired, how food was cooked, consumed, and later disposed of, and the more functional aspects of foodway practices. The in-depth study of artifacts and ecofacts related to diet and subsistence sheds light on the Native-lived experience in the mission, revealing interactions between mission laborers and the environment. 9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9=9==9=9=9=9=9=9= About the Author Kaitlin Brown completed her doctoral degree in Anthropological Archaeology at UC Santa Barbara in September 2021. Her research focuses on the formation and maintenance of Native communities in California under waves of Spanish and Mexican colonialism by investigating socio-economic change and indigenous persistence. She led an archaeological feld school to uncover the indigenous past from Mission La Purísima Concepción that investigated the Chumash rancheria 'Amuwu. In collaboration with participants of the feld project, the results were presented at the 55th annual meeting of the Society for California Archaeology and make up the body of this published work. She is currently teaching anthropology courses at California State University, Channel Islands.
