About this map

Amboy and Chelatchie anchor this study of the southwest Washington landscape, where the Clark County and Cowlitz County border intersects the Lewis River. The topography is dominated by the expansive Lake Merwin, with Speelyai Bay reaching into the northern timberlands. Settlement patterns follow the lowlands of the Chelatchie Prairie, a distinct geographic break between the prominence of Green Mountain and Donegan Mtn.

Evidence of local aviation and industry is preserved through features like the Mount St Helen's Aero Ranch and Walter Sutton's Private Strip, alongside the Columbia Tie Mill Pond. Water management for the region is traced through the Fassett Reservoir and Leroy Anderson Reservoir, which feed into a complex network of creeks including Cedar Cr and Chelatchie Cr. This survey documents a transition from established rural homesteads to modern infrastructure, including the Yale and Woodland Park communities along the northern shoreline.
