At Mount Rainier National Park, Baumann takes his audience to Central Washington to witness one of the most geologically tenuous landscapes in America. The mountain and region have been shaped by volcanic activity and geologists anticipate its next blast. The mountain itself is an active volcano encased in over 35 square miles of snow and ice. The journey includes examples of old growth forests and sub- alpine meadows. On his journey, Baumann interviews several Native Americans from the region, including Lewis Squallysr; archaeologist Lee Taylor details the native and contemporary human history. Baumann concludes this episode with a riverside painting of Mount Rainier.
