Devil's Tower Monument, Wyoming

MAY 08, 2016

While we stayed in Spearfish, we also took a short trip to Wyoming to see Devil's Tower. A friend in Austin had recommended that we see this and I questioned whether it would be worth the two hour trip out of our way.

“WOW!” I found it amazing! Like many places, this is one of those that you cannot truly appreciate until you see it for yourself. Unfortunately, we did not make it to the visitor's center early enough to get to check it all out but they have a very nice interpretive trail that goes all the way around the monument.

And you should definitely go all the way around. Each side looks a little different.

And the geology of it is so interesting. It was formed by magma that cooled underground and then was later exposed by erosion. And when the magma cooled, it contracted into hexagonal columns separated by vertical cracks. When those columns erode away or fall off, they leave that scratch-like appearance down the sides of the monument.

The natives tell a story about some children who climbed up there trying to escape from giant bear and the scratch marks down the side are from the bear's claws in his attempt to get them.

It is also interesting that the monument is still growing (due to erosion from the Belle Fourche River) but of course the top is slowly eroding away as well. Currently it stands at 867 feet.


So just in case you couldn't tell, it was DEFINITELY worth a two-hour drive! ;)
