 | | In the past, the Rocky Mountains had a higher level of volcanic activity; nowadays, the range only has one area of volcanism (the supervolcano underlying Yellowstone National Park in Wyoming, possibly the world's largest volcano), although rift volcanism has occurred relatively recently near the Rockies' southern margin in New Mexico. |
 | | Numerous volcanoes can be found throughout the Alexander and Aleutian Islands extending south and west of the Alaskan mainland. |
