2021 Map of Willis Ridge

USGS Topo · Published 2021

About this map

Willis Ridge and Shimmin Ridge dominate the rugged interior of Mendocino County, where the landscape is defined by steep drainages and isolated peaks. This 2021 survey illustrates a region largely shaped by the winding courses of the Eel River and Outlet Creek, which cut deep through the mountainous terrain. The small settlement of Farley sits near the northwestern corner, while the low-lying Wheelbarrow Valley provides a rare stretch of relatively level ground to the south.
