1989 Map of Armstrong Creek

About this map

Colville Indian Reservation land dominates this high-altitude terrain in the late 1980s, revealing a landscape defined by complex geology and remote waterways. Along Mineral Ridge and the descent toward Kroll Canyon, a dense concentration of mining activity is visible, including the Sailor Boy Mine, Little Johnny Mine, and numerous unnamed shafts and prospects. These sites suggest a period of intensive subterranean exploration in the hills above the Columbia River.
