2020 Map of Anderson Lake

About this map

The Nisqually River flows along the northern edge of this high-elevation terrain on the border of Pierce and Lewis Counties. This landscape is defined by its complex drainage network, where the N Fork Mineral Cr and Reese Cr carve through the forested ridges. Central to the sheet is Anderson Lake, a distinctive high-country water body reached by a network of local forest roads. Near the northern boundary, the National Mill Pond suggests the region's historical and ongoing connection to the timber industry, while the south is anchored by the North Fork Swamp. The survey captures a moment in the modern era where limited infrastructure like Osborn Rd and Blue Bird Rd provide the only significant access into this otherwise densely contoured wilderness.
