Yellowstone and the Cascades do get a lot of the attention when it comes to North American volcanoes, but they are surely not the only places where we might find active volcanoes across the continent. Now, I can’t highlight all the “hidden” volcanic areas in the United States, but I will talk about a few gems that most people don’t realize are potentially active volcanic areas. You can check out the USGS Volcanic Hazard Program’s map of the volcanoes it monitors (which includes the status of many of these volcanoes — all green currently).
