Missouri Buttes + Devil’s Tower

The Exposed Volcanic Necks in this image are all related in space and time. Once deeply buried volcanic conduits to the surface. Each of the 4 peaks stands eroded at the surface. These pipes carried magma to the surface as lava/ash in four volcanos popping off at the surface . The rock we see here froze solid in that neck and cooled. We know this was deep as the column of rock in the Devils Tower cooled very slowly allowing the columns of rock the National Monument is famous for. Being our nations first national Monument is the moniker that Devil’s Tower and surround area carry. Wyoming and all that

Being 40 miles away from the tow and the buttes somewhat closer, this becomes a terribly long shot to actually be able to resolve the columns on the tower. There is SOME columnar jointing in the Missouri Buttes. Emplaced closely in time and space does not say they were coterminous in their eruptions. . We don’t know their exact schedule.

Phenolitic Porphyry is the name of the rock. It cooled into big 6 foot in diameter crystals up the length of the tower. I used one of several possibilities all related to volcanic activity to describe the tower as volcanic necks. There are multiple configurations and possible variations in this discussion I won’t get into here but feel free to google devils tower origin to discover more.

Location: The Pass at Rockypoint Wyoming, Trail Creek Road, NE Campbell Country
