Countless snow-clad mountain spires dwarf narrow glacial valleys in this 505,000-acre expanse of the North Cascades, which encompasses three diverse natural areas. North Cascades National Park is the core of the region, flanked by Lake Chelan National Recreation Area to the south and Ross Lake National Recreation Area to the north; all are part of the Stephen T. Mather Wilderness Area. It’s a spectacular gathering of snowy peaks, glacial meadows, plunging canyons, and cold deep-blue lakes. Traditionally the lands of several American Indian tribes, it's fitting that it's still completely wild—and wildlife filled.
