DEVILS TOWER
The Devils Tower is a 867 foot rock formation in the northeastern Wyoming.The Devils Tower which is an igneous intrusion or laccolith in the Bear Lodge Mountain near the Hulett and Sundane in the crook Country, the northeastern Wyoming is above the Belle Fourche River. The Devil Tower which is made of Phonolite porphyry which is an igneous rock, which means that it is formed as magma or lava cooled. The first declared United States National Monument was the Devils Tower, which is found to be established 24th September 1906, by the Theodore Roosevelt the president. The Monument's boundary which encloses an area of 1,347 acres. The Devil's Tower got its name in 1875 during an expedition led by the col. The Richard Irving Dodge's interpreter misinterpreted the name to mean Bad God's Tower, which then becomes has the Devil's tower. The landscape surrounding the Devils Tower is composed mostly of the Sedimentary rocks. During the Triassic period the oldest rock visible in Devils Tower National Monument were laid down in a shallow sea. The dark red sandstone and maroon siltstone, which is inter bedded with the shale, which can be seen along the Belle Fourche River. The redness of the rock is due to the oxidation of iron minerals. This rock layer, which is known as the spearfish Formation. There is a thin band white gypsum above the Spearfish formation, which is called as the Gypsum Spring Formation. The layer of gypsum was deposited during the Jurassic period. The Devils Tower which is made of Phonolite Porphyry. The Phonolite Porphyry which is an igneous rock, that means it was formed by the Lava or Magma cooled. The magma which formed Devils tower cooled, which condensed into the columns. The columns which are formed by the Devils Tower are Hexagonal (which means it has six sides). The Devils Tower is formed by the Magma, even through it is not a part of a volcano. The Geologists says that the Devils tower is an igneous intrusion, it means that a place on the Earth's mantle formed by the magma between the chunks of sedimentary rock. The Devils Tower which was not visible for million of years. As the water and wind slowly eroded the surrounding landscape did the igneous intrusion emerge, even today's the landscape continues to erode, worn away by the wind, precipitation and also the nearby Belle Fourche River. The base of the formation which is cluttered with the scree- rubble, boulders, and the fragments of the columns which has broken off the tower.
