Rancho Bolsa de Tomales was a Mexican land grant in present day Marin County and Sonoma County, California given in 1846 by Governor Pío Pico to Juan Nepomuceno Padilla.[1] The name means "the Pool of the Tomales Indians," which referred to Burbank’s Lake. The grant extended along the Pacific coast from Estero de San Antonio south to Walker Creek, and encompassed present day Tomales. Stemple Creek transversed the property.[2][3][4] The land claim was rejected as fraudulent by the US Supreme Court.
