Okay, so a billion years ago a volcanic plume tried to fuck up Michigan and failed, causing the Midcontinent rift system. Then it chilled out for awhile before getting squished by glaciers into going east and making the Adirondack mountains about 20 million years ago. Then it went west due to daylight savings time and made Yellowstone about 2 million years ago.
