Mitten Butte Volcano Illusion
So I wake up the other morning and much to my surprise, was a local pyramidal hillock that was blowing it’s top. The steam was rising, the cauldron boiling. I anticipate pyroclastic flows, lahars, glowing red hot clouds and other volcanic manifestations similar to what buried Pompeii. Ash should start falling any moment. Maybe “Sneaky Pete” the windmill will save the day and blow the ash away…
Back to my normal programming: Geologic Musings:
OK, this is NOT a volcano. It takes a properly positioned camera lol. Those are normal clouds up in the sky. Yellowstone is not blowing up. The Devil’s Tower/Missouri Butte Volcanic Neck field about 50 miles to my southeast has not reactivated. No, the Laramide Orogeny has not started back up just yet.
That Butte (called Mitten Butte), is made of layers of river sands stacked on top of one another. The volcanic shape is a result of a hard cap rock which resisted erosion better than every thing else between it and myself. All that rock has been removed by erosion. It is a erosive remnant of all the material that used to surround the hill. Hundreds of feet if not thousands of feet (depending on your location) of sediment has been removed around here. Remember Devils Tower? That used to be a mile or so deep. Now it sticks up 1267 feet above the Belle Fourche River. That river system essentially removed enough material to expose the harder tower. Same process here except just the top of the hill is harder rock.
Location: Bliss Dinosaur Ranch, Wyoming/Montana borderlands (Wyotana).
