The protection, study and management of the park's natural resources and processes is essential for achieving the park's purpose and mission goals. The park includes outstanding geologic and hydrologic resources that represent key physical elements in the park ecosystem, including glaciers and snowfields, geomorphic features such as watersheds and landforms, soils, and paleoecologic deposits. Glaciers, snowfields, watersheds, and soils are especially sensitive to air pollution and climatic change.
Glaciers carve through the landscape of Mount Rainier, fuel the park rivers, and are a measuring stick for climate conditions.
Seismicity is the study of earthquakes. Earthquakes are monitored on Mount Rainier as one way to track volcanic activity.
