About this map

Mark West Springs serves as a central point in this landscape where the boundaries of Napa Co and Sonoma Co converge. The terrain is defined by the high ridges of the Mayacmas Mountains and Sugarloaf, dropping into the fertile reaches of Knights Valley and Franz Valley. This era of the mid-2010s shows a complex network of rural routes like Porter Creek Rd and Calistoga Rd that connect isolated settlements and preserves.

Water plays a critical role in the geography, with Mark West Cr and its tributaries, including Franz Cr and Porter Cr, carving through landmarks like Devils Kitchen and Gates Canyon. From the heights of Chalk Mtn to the residential pocket at Redwood Hill, the map documents the modern footprint of these historic wine-country uplands, including established areas like Foothill Ranch and the protected lands along Pepperwood Preserve Rd.
