About this map

The Quinault River sweeps across the southern portion of this Grays Harbor County landscape, providing the primary drainage for a network of mountain streams. Rising toward the northeast, the Olympic Mountains and Thimble Mtn dominate the terrain, their slopes carved by the S Fork Salmon River, Huckleberry Cr, and Boulder Cr. The area is characterized by the complex Bureau of Indian Affairs road network, with dozens of routes such as Bia RD 9200 and Bia RD 9400 crisscrossing the timbered valleys.

In the southeast, the terrain levels out at Chow Chow Prairie, a distinct geographic break from the high ridges to the north. This survey illustrates the modern management of these tribal lands, tracing numerous named tributaries like Ten O'Clock Cr, Lunch Cr, and Joe Cr. The map is a detailed record of the intersections between water, topography, and the specialized transportation infrastructure required for this corner of the Pacific Northwest.
