2020 Map of Gilbert

About this map

Gilbert sits at a high-elevation junction of the Twisp River headwaters, serving as a focal point for mountain travel in the eastern Cascades. This area is defined by its industrial and recreational history, anchored by the Crescent Mine near Crescent Mtn and its proximity to the Okanogan National Forest. The landscape transitions from high peaks like Abernathy Peak and Reynolds Peak down to protected alpine basins within the Lake Chelan National Recreation Area. Traditional mountain passes, including Twisp Pass and Copper Pass, provide historical transit routes through the high ridges, while a network of alpine water bodies like North Lake and Louis Lake feed the glacial drainage system. The map reflects a modern management era of these wilderness corridors, documenting the intersection of the Okanogan and Chelan County lines.
