1990 Map of Thimble Mountain

About this map

The Quinault Indian Reservation dominates this landscape in the early 1990s, defined by the winding course of the Quinault River and its numerous tributaries. The map documents a specific intersection of indigenous territory and historic geopolitical lines, most notably the 1818 Treaty Boundary visible in the northern portion of the quadrangle. The terrain transitions from the river valley floor toward the heights of Thimble Mountain, with the hydrological network including South Fork Salmon River, Crane Creek, and O'Clock Creek. Evidence of earlier industrial or transit activity is marked by an Old RR Grade and several resource extraction sites like Borrow Pit and various Gravel Pits. A lone Water Tank stands near the base of the mountain, indicating localized infrastructure in an otherwise largely undeveloped wilderness area.
