The Miwok Archeological Preserve of Marin (MAPOM) was founded in 1970 as a result of community involvement in the excavation of a Coast Miwok village site.

Through a diverse range of programs and cooperative efforts, with groups such as the Federated Indians of Graton Rancheria (Coast Miwoks) and the Point Reyes National Seashore, MAPOM seeks to promote accurate knowledge of the Coast Miwok Indians, the first people of Marin and southern Sonoma counties.
