Jackson State Forest encompasses much of this timber-rich Mendocino County landscape, where the North Fork Big River and the East Branch North Fork Big River converge. The topography is defined by significant ridges and clearings, such as Greenough Ridge and Bowman Ridge, interspersed with family-named clearings like Upper Ranch Opening and Hans Ottoson Opening.
