About this map

Cherry Grove sits at the eastern edge of this topographical study, where the Tualatin River begins its descent through the Coast Range foothills. This 2020 map documents a landscape defined by water management and industrial timber activity, illustrated by the presence of the Hillsboro Reservoir, Yamhill Reservoir, and Turner Cr Reservoir. The topography is marked by several prominent elevations including Homestead Ridge and Blind Cabin Ridge, which divide the numerous drainage basins of Roaring Cr and Turner Cr.

A network of specialized access routes like Stinson Tree Farm Rd and NW Flora Mainline indicates the ongoing importance of forestry in the region. Waterfalls such as Hayes Falls, Lee Falls, and Little Lee Falls are noted along the upper reaches of the river system. The boundary between Washington Co and Yamhill Co bisects the map, showing how these administrative lines follow the high ground of Hagerty Ridge.
