1989 Map of Thirteenmile Creek

About this map

The Colville Indian Reservation and Colville National Forest meet in this 1980s topographic study, defined by the winding course of the Sanpoil River. The terrain is characterized by a series of significant drainage systems that feed into the river valley, including Thirteenmile Creek, Seventeenmile Creek, and Nineteenmile Creek. This provisional map captures the region's managed landscape, where federal forest lands and reservation boundaries overlap. Evidence of industrial activity and infrastructure is found at the Gravel Pit and the Gaging Sta BM 1952 along the western riverbank. The drainage names, from Rattlesnake Gulch to Twentythree Mile Creek, follow a sequential numbering pattern typical of early transit and exploration routes through this part of Ferry County.
