The surviving Muwkema Ohlone people continued to maintain their Indian culture. Although entirely landless by the 1920s, they like the other Ohlone/Costanoan tribal communities continued to survive as distinct Indian communities and speak their respective languages as late as the 1930s.

It is from the work of linguist-cultural anthropologist J. P. Harrington, who worked in the Ohlone region from 1921-1939 with the last fluent elderly speakers of the Ohlone languages, that we know much about the culture and changing world of the Costanoan/Ohlone people. Presently, the grandchildren of Harrington's linguistic and cultural consultants comprise the Elders and leadership of the Muwekma Ohlone Indian Tribe of the San Francisco Bay.
