Russian River drainage patterns define the geography of Mendocino County south of Ukiah, where agricultural valleys meet the rising slopes of the Mayacmas Mountains. This 2015 dataset captures the transition from the city’s southern fringe and the Ukiah Municipal Airport to the more rural expanses of El Roble and the Ukiah Rancheria. The landscape is etched by numerous tributaries including Howell Cr, Robinson Cr, and McNab Cr, which have carved out the varied topography between Cleland Mtn and Elledge Peak. Further south, the settlement of Largo sits near Knight Hill, illustrating the enduring rail and road corridor that follows the river's path. Private ranch lands are reflected in names like Nelson Ranch Rd and Bus McGall, providing a modern record of land use and family-named landmarks in the Ukiah Valley.
