Tomales Bay marks the southwestern corner of this coastal landscape, where the terrain rises from the shoreline into a complex system of ridges and valleys defined by historic land grants. The map documents numerous Spanish-influenced Mexican land grants and their subdivisions, including several areas designated as Nicasio (Halleck) and Soulajule (Vasquez). These divisions often carry the names of specific nineteenth-century landowners like Frink and Reynolds, Brackett, and Gormley, providing a detailed record of historic property boundaries and family lineage in the region. In the northern reaches, the Two Rock Ranch Station Military Res straddles the county line, while water features like Chileno Creek and Laguna Lake navigate the valley floors between prominent landmarks such as Three Peaks.
