I doubt this is accurate about NM. IDK about Monument Valley. Our volcanoes are pretty much extinct and I would have remembered my geology prof telling us about any dormant or active volcanoes in our state. I'll have to ask my live-in geologist when I call him later. We do have a lot of ancient volcanic activity i.e Shiprock and The Valdez Caldera and some as recent a 10,000 years ago (I was at the Land of Fire and Ice a few weeks ago) and Malpais is an example of an ancient, but relatively recent, lava flow that cooled. Volcanic plugs are just remains of an ancient magma vent where it cooled and then the landscape surrounding it eroded away, a typical geologic process.
