Episode Overview

This episode explores the timeline of human presence in North America, highlighting the profound impact of natural resources like gold and oil on the landscape. These elements have significantly altered the land, rivaling the geological processes that formed it. Yet, geology poses future threats as well; the Cascadia fault line in the Pacific Northwest could trigger a devastating earthquake and tsunami, while the super-volcano beneath Yellowstone holds the potential to devastate vast areas of the continent if it were to erupt.
