1982 Map of Shale Slough

About this map

The Quinault River dominates this coastal landscape on the Quinault Indian Reservation, winding through a network of secondary waterways including California Slough and Shale Slough. This 1980s-era mapping records the intricate drainage patterns of the coastal lowlands, where the Prairie Creek and Moclips River systems carve through the terrain before reaching the shore. The western edge is defined by the Pacific Ocean, protected by the Copalis National Wildlife Refuge and the Washington Islands Wilderness.
