About this map

English Hill rises above a landscape defined by rolling agricultural corridors and a network of small settlements at the southern edge of Sonoma County. This survey shows the rural character of the area where Bloomfield and Two Rock serve as community anchors. The terrain is bisected by the winding courses of Americano Cr and Stemple Cr, which drain toward the coast, shaping the layout of historical ranch roads like Valley Ford Rd.

Genealogists will find significant value in the documentation of several family and community burial grounds, including Canfield Cem near Knowles Corner and the Two Rock Presbyterian Church Cem. The map clearly delineates the border between Sonoma and Marin Counties, capturing the modern footprint of longstanding hamlets such as Cunningham, Hessel, and Turner as they appeared in the early 21st century.
