The Awaswas lived in the Santa Cruz Mountains and along the coast of present-day Santa Cruz County from present-day Davenport to Aptos. Awaswas became the main language spoken at the Mission Santa Cruz. However, there is evidence that this grouping was more geographic than linguistic, and that the records of the "Santa Cruz Costanoan" language in fact represent several diverse dialects.
In 2012, Amah Mutsun Tribal Chairman Valentin Lopez stated that "his great-great-grandmother was the last of the Awaswas speakers."
