The South Fork Chehalis River carves through the landscape near the small community of Wildwood, where numerous tributaries like Wilson Creek and Sep Creek feed into the main waterway. This 2023 survey illustrates the rugged drainage patterns of the region, defining the transition from the Lewis County highlands into the northern reaches of Cowlitz County. To the south, the settlement of Ryderwood sits adjacent to Ryderwood Pond and Campbell Creek, serving as a primary local hub at the foot of Pumphrey Mtn. The map traces a network of timber and access roads, including Wildwood Rd and Brim Creek Rd, which navigate the steep elevations of Stony Grade and Point Hill. Family history researchers can locate the Snow Cem in the northeast, a quiet landmark situated near the headwaters of the North Fork Brim Creek and Laughlin Creek.
