Bailey Ridge and the surrounding Mendocino County highlands define this landscape, where the headwaters of the South Fork Big River and the South Branch North Fork Navarro River descend through steep drainage basins. This modern topographic study reveals a terrain shaped by historical logging and land use, evidenced by the Shingle Mill and several clearings including Montgomery Flat and Castle Garden. Significant travel routes like the Comptche Ukiah Rd and the Masonite Industrial Rd traverse the ridges, connecting small settlements like Montgomery and Low Gap. The map details a complex network of creeks, such as Daugherty Creek and Gates Creek, alongside named local landmarks like Wohlis Pass and Horsethief Opening, providing a comprehensive look at the contemporary character of these coastal mountains.
