About this map

Mark West Springs serves as a focal point in this portion of the northern California landscape, where the rugged topography of the Mayacmas Mountains meets the valley floors. The map details a complex network of canyons and ridges, including Gates Canyon and Shiloh Ridge, which define the drainage patterns for Mark W Cr and Franz Cr. This 2021 survey documents the persistent rural and residential character of the region, specifically around Franz Valley and Knights Valley.

Transport and land use are centered on winding corridors such as Petrified Forest Rd and Porter Creek Rd, which navigate the elevation changes near Chalk Mtn and Telegraph Hill. Local history is reflected in names like Franz Valley School Rd, suggesting the historical locations of community infrastructure. The northern reaches of Santa Rosa appear at the southern margin, showing the city's interface with the foothills near Redwood Hill.
