About this map

Chileno Valley and the surrounding coastal ridges of Marin County are defined here by a series of distinct land divisions named for early California families and ranchers. The map reveals a landscape of complex property history, specifically within the Nicasio and Soulajule tracts, including subdivisions like Nicasio (Frink and Reynolds) and Soulajule (Gormley). These labels provide a clear genealogical link to the 19th-century land grants and subsequent partitionings that shaped West Marin.

The northeastern corner of the quadrangle is anchored by the Two Rock Ranch Station and its associated Military Res, while the southwestern edge touches the waters of Tomales Bay near Millerton. Water remains a vital element of this agricultural terrain, with drainage systems like Walker Creek and Salmon Creek winding through the canyons toward the coast. Collectors and historians can trace the transition from open grazing land to more regulated military and water-management areas, marked by numerous small reservoirs and the boundary between Sonoma and Marin counties.
