About this map

Adelaida and the surrounding wine country of San Luis Obispo County are defined by a complex network of creeks and ridgelines in this 2015 study. The settlement itself sits near the intersection of Adelaida Rd and Adara Rd, while the Adelaida Cem remains a significant point of local heritage to the northwest. The landscape is carved by several major watercourses, including San Marcos Cr, Las Tablas Cr, and Mustard Cr, which feed into the nearby reservoir system.

Infrastructure in this rural corridor includes the private Mc Millan Airport and a series of winding roads like Nacimiento Lake Dr and Peachy Canyon Rd that follow the natural topography. Geological landmarks such as Chimney Rock, Hidden Mountain, and Black Key provide distinct vertical relief in an area primarily used for viticulture and ranching. The map preserves the township and range lines that have governed land ownership here since the late 19th century.
