Snow-Capped Mountains Shape Northwestern Washington

Snow‑capped peaks sculpted by deep river valleys dominate the landscape of northwestern Washington, where the Cascade Range rises sharply above a network of waterways that have cut dramatic gorges over millennia. The region includes prominent summits such as Mount Baker and Mount Rainier, whose glaciated ridges are fed by the Skagit, Stillaguamish and other tributaries that flow toward the Puget Sound and the Pacific Ocean.

These geological features support diverse ecosystems and attract recreation, with national parks and wilderness areas preserving the terrain while providing access for hiking, climbing and scientific study. The interplay of high alpine environments and river valleys continues to shape local climate, water resources and land use planning across the state.
