2017 Map of Sanderson Creek

About this map

The Columbia River carves a dramatic border between Douglas and Okanogan counties in this mid-2010s survey, defined by a series of powerful water features including Nespelem Rapids, Equilibrium Rapids, and Monaghan Rapids. The terrain is characterized by significant elevation changes, with Deep Canyon and Kaiser Canyon cutting through the landscape toward the riverbank. This map captures a rural and industrial interface where remote water bodies like Black Lake, Rock Lake, and Smith Lake are connected by a network of local roads such as Siebold Hill Rex Rd and Pendell Rd. The prominence of Sanderson Creek and the river deposits at Buckley Bar highlight the geomorphology of this high-plateau region, providing a detailed look at the hydrology and land use patterns before recent environmental shifts in the Columbia River basin.
