'''Devils Tower''' is a monolith and popular tourist attraction in the state of [[Wyoming]], rising 1267 feet.<ref>http://www.nps.gov/deto/</ref> It was declared America's first national monument by [[Theodore Roosevelt]] in 1906.
Devils Tower was formed by molten igneous rock forcing its way into the area's sedimentary rock, cooling before reaching the surface, and the sedimentary rock being eroded away.<ref>http://www.nps.gov/archive/deto/geology.htm</ref> Scientists have debated for many years exactly what process brought the molten igneous rock up. One early explanation was that it was the remains of a laccolith - a mushroom-shaped underground formation. Another theory is that Devils Tower is the remains of a volcano, though no other evidence of volcanic activity has been found in the area.
The formation's official name contains no apostrophe due to a never-corrected clerical error.<ref>http://www.nps.gov/deto/naturescience/index.htm</ref>
