The physical properties of Mount Rainier as an active volcano with an active glacial system, extreme weather patterns, and high volumes of precipitation make the park inherently vulnerable to natural disaster. Our biggest threat in most areas of the park are Geohazards which are events resulting from geological activity in the park taking the form of mudslides, debri flows, and rapid flooding. It is the volunteer's responsibility to know the probability of these events in the area they are working in, the warning signs, and how to get to safety. Detailed information can be found on our Geohazards Page. Ask your supervisor about evacuation routes for your specific location as well as the locations of lahar packs that are located in all office and visitor centers.
