Nature & Science

North Cascades National Park Complex spans the Cascade Crest from the temperate rainforest of the wet west-side to the dry ponderosa pine ecosystem of the east. The park encompasses landscapes with over 9,000 feet of vertical relief. There results a high diversity of plants, over 1,600 species so far identified, and many other organisms adapted to a wide spectrum of habitats.

The relatively new mountains, glaciers and streams of North Cascades lie near a dynamic interface of tectonic plates and provide an opportunity to study geologic processes unfolding through time. Geologists and others seek answers to questions of global climate change, mountain building and erosion, volcanism, glaciation, stream dynamics, and more.
