2017 Map of Mount Defiance

About this map

Cook and the community of Mill A anchor the northern banks of the Columbia River, where timber and waterway commerce shaped the landscape of the Columbia River Gorge. The river itself, charted here as Lake Bonneville, serves as the state boundary between Washington and Oregon, bisected by the Cook Point Range Channel. This 2017 survey details a terrain defined by steep elevations and critical infrastructure, including the Little White Salmon National Fish Hatchery and its associated Little White Salmon Hatchery Reservoir.
