2020 Map of Mount Defiance

About this map

Mill A and the nearby flats of Mill A Flat and Mill B Flat anchor the northern landscape of this Columbia River Gorge corridor. The terrain is defined by the steep elevation change from the shores of Lake Bonneville up to the high peaks of Mt Defiance and Shellrock Mtn. This area serves as a critical junction for water management and conservation, featuring the Little White Salmon National Fish Hatchery near Drano Lake and the Green Point Lower Reservoir to the south. The mapping detail shows a dense network of mountain hydrology, from the cascading Lancaster Falls and Starvation Creek Falls to alpine water bodies like Warren Lake and Bear Lake. These features reflect a landscape heavily shaped by the boundaries of the Gifford Pinchot National Forest and Mount Hood National Forest, where timber history and watershed protection intersect.
