About this map

Knights Valley and the small settlement of Kellogg anchor the southern reaches of this landscape where the Mayacmas Mountains dominate the terrain. The presence of Evergreen Cem near the junction of Franz Valley Rd provides a specific point of reference for local family history and genealogy. Rising to the east, the massif of Mt Saint Helena marks the triple point of Sonoma, Lake, and Napa counties, a significant geographic landmark that defines the regional drainage patterns.

Watercourses such as Redwood Cr and Maacama Cr carve through the deep canyons, while names like Bacon Flat and Turner Flat suggest the few pockets of level ground utilized in this mountainous area. Legacy ranching operations and early access routes are preserved in the labeling of Mc Micking Ranch Rd and Jackson Ranch Rd, tracing the historical footprint of land use across the northern California ridges.
