Devils Tower Facts

There are a number of interesting Devils Tower facts to consider. For starters, this fascinating rock formation in northeastern Wyoming was the first United States National Monument. President Theodore Roosevelt established it as such back in 1906. Prior to this, Devils Tower served as an important landmark for Native American tribes, and it is easy to understand why. The monument is an amazing thing to behold, partly because of the fact that it stands much higher than the surrounding terrain.

In regards to Devils Tower geology, the fascinating rock formation is commonly classified as a monolithic igneous intrusion. Geologists are also known to label it as a volcanic neck, a volcanic plug or a laccolith. Chances are good that it was formed when magma hardened within the vent of an active volcano. Over time, the surrounding volcano crumbled, leaving the erosion-resistant plug behind. This is just one theory, however, and there are others. Suffice it to say that the Devils Tower geology is a bit of a mystery. Most of the theories are based around the same general idea, however, and there is no denying that it is a mass of igneous rock.

Devils Tower stands 1,267 feet taller than the terrain that surrounds it. It is also interesting to consider that its summit rises to an elevation of 5,112 feet above sea level. The first people to document its existence were part of an expeditionary team that was led by Captain W.F. Raynolds. The year of this original documentation was 1859, and the expedition was dubbed the Yellowstone Expedition. As for the Devils Tower name, it was coined by Colonel Richard Irving Dodge. He visited the site with a scientific survey party in 1875. Eighteen years after that, the first known ascent of the igneous intrusion occurred. People have been climbing Devils Tower ever since.
