The North Cascades ecosystem extends from Snoqualmie Pass to the Fraser River valley in British Columbia, encompassing rugged peaks, ancient forests, arid steppes, and glacier-fed waterways.

As one of the largest intact ecosystems in the contiguous United States, the North Cascades are home to a number of threatened and endangered species. Through citizen activism, Washington’s North Cascades National Park was created over 40 years ago. However, wild landscapes that many people believe to be inside the national park boundaries or federally designated wilderness areas remain unprotected.
