The Two Rock Ranch Station Military Res sits at the northern edge of this Marin County landscape, a region defined by ranching land divisions and rolling ridges. The map meticulously documents the complex land ownership patterns through parenthetical labels like Nicasio (Halleck), Soulajule (Vasquez), and Soulajule (Gormley), reflecting the legacy of Spanish and Mexican land grants. To the west, the reach of Tomales Bay begins to influence the terrain, while the drainage of Walker Creek and Chileno Creek carves through the hills. This 1954 survey, with its 1971 revisions, highlights the reliance on water management in the San Antonio Valley, marked by numerous unnamed reservoirs and the sprawling Laguna Lake. The terrain is punctuated by distinctive high points such as Three Peaks and the Nicasio (Frink and Reynolds) Ridge, offering a detailed view of the coastal range before modern development altered the rural character of this ranching corridor.
