1967 Map of Sixmile Creek

About this map

The Clearwater River carves a deep valley through this northern Idaho landscape, marking the boundary between Lewis and Idaho counties. This 1967 field-checked survey reveals a rugged geography defined by sharp drainage patterns, where Sixmile Creek and Effie Creek feed into the main river channel from the west and south. The high ground of the Camas Prairie overlooks the river's eastern banks, while the western plateau is marked by a scattered infrastructure of a Substation and a series of extractive sites including a Gravel Pit and a Borrow Pit. The map demonstrates the era's reliance on a network of unpaved roads and a Jeep Trail to navigate the steep descent from the timbered ridges down to the water's edge. This document preserves the land's character at a time when industrial footprints were localized to small-scale pits and essential utility crossings.
