Glacier Peak is the fourth tallest mountain in the state of Washington, as well as the most isolated volcano in the Cascade range. Centering this region, the lands encompassed within are bound by Puget Sound, the Stilliguamish and Sauk River basins, the Highway 97 and the Chelan and Sawtooth Mountains on the east and the Wenatchee and Skykomish River basins on the south.
Aside from the ice-clad volcano at the center of the region, the area is most notable for the Glacier Peak Wilderness, the largest such protected area in the state and one of the most inaccessible parts of the Pacific Northwest. Because a significant portion of this region falls within such a wilderness, the regionâ€™s waterfalls are largely undocumented. The southern extent of the most rugged parts of the North Cascades extend through the heart of the region and with the accompanied heavy glaciation comes several lofty waterfalls. Access to the best of the known waterfalls is difficult at best, and considering how much of the area has not been properly surveyed, one can only speculate at the treasures hidden deep in the mountains.
