NPS Photo 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. 
GlaciersGlaciers carve through the landscape of Mount Rainier, fuel the park rivers, and are a measuring stick for climate conditions. 
VolcanoesMount Rainier is a active volcano. Lava flows and eruptions have shaped the landscape in the past, and evidence can still be seen today. 
SeismicitySeismicity is the study of earthquakes. Earthquakes are monitored on Mount Rainier as one way to track volcanic activity. 
AggradationAggradation, the process of rivers filling with rocky debris, can play a big role in flooding and other river behavior.
