About this map

Chelan Mountains dominate this high-elevation landscape within the Wenatchee National Forest, where steep drainages and alpine basins define the terrain. The northern reaches of the quadrangle include a portion of Lake Chelan and the Lake Chelan National Recreation Area, transitioning into the protected Glacier Peak Wilderness. This 1988 provisional edition captures the watershed patterns of the Cascades, showing the descent of Railroad Creek and Wolverine Creek toward the lake, while the Entiat River headwaters emerge in the southwest.
