About this map

Colville Indian Reservation land dominates this 1989 provisional survey, characterized by a complex network of canyons and high-elevation mining claims. The landscape is deeply incised by Hudnut Canyon, Panama Canyon, and Kroll Canyon, which descend toward the Columbia River and Rufus Woods Lake. These rugged corridors were historically active sites of mineral extraction, evidenced by the high concentration of prospects and named operations such as the Sailor Boy Mine, Apache Mine, and Little Johnny Mine near Hilo Hill.

Water resources are concentrated in the high meadows and specialized drainage systems, including Armstrong Meadow and Grant Lake in the north. The southern boundary follows the river's path, where the topography drops sharply toward Bissell Flat. Landmarks such as Multnomah Falls and Spray Falls along the Nespelem River tributaries highlight the significant vertical relief and hydraulic activity of the Okanogan County interior during the late 20th century.
