1989 Map of Copper Mountain

About this map

North Cascades National Park dominates this high-altitude landscape along the border between Washington and British Columbia. The terrain is defined by a dense network of glacial drainage, where the Chilliwack River and Little Chilliwack River carve through steep ridges. This 1989 provisional survey documents the primitive infrastructure used to navigate the backcountry, including a Cable Car Crossing and a Foot Bridge across the water. Notable peaks like Copper Mtn, Middle Peak, and Indian Mountain overlook alpine basins containing Hanging Lake, Egg Lake, and Copper Lake. The map illustrates the transition from the international boundary at the United States and Canada border south toward Red Face Mountain and Easy Ridge, marking a wilderness managed primarily for preservation and remote access.
