Most of the area around Devils Tower consists of sediments. In the Devils Tower National Monument, the oldest cliffs were placed in a flat ocean in the middle to later Triassic times 225 to 195 million years ago. It is called the spearfish formation. Hulett-Sandstein, also part of the Sundance Formation, is made of amber, fine-grained sandstein.
It is weatherproof and creates the almost perpendicular rocks that surround the tower. Carpenter and Russell study the Devils Tower in the latter part of the nineteenth centuary and come to the conclusions that it was created by a magmatic burglary. Contemporary gemologists are in agreement that it was created by the penetration of magmatic materials, but not exactly how this procedure works.
Some believe that the melted rocks from the tower may not have appeared; others are confident that the tower is all that is left of what was once a large volcan. By 1907, Darton and O'Hara agreed that the Devils Tower must be an extinct relic of a laccolite. Laccolite is a large amount of eruptive rocks that penetrates through bedrock sediments without accessing the upper layer but forms a curved curvature in the upper one.
There are other theory that the Devils Tower is a vulcanic connector or the necks of an extinguished vulcano. Probably, if the Devils Tower is a cone of a vulcano, the volcanoes it produces - vulcanic dust, streams of water, vulcanic rubble - would have been removed long ago. Somewhat of the same old Devils Tower specimens have been found elsewhere in Wyoming.
A phonolith porous stone, which has penetrated about 40 %, is the magmatic element that makes up the tower. Five million years ago a pale to darkgrey or greenish-grey eruptive stone with striking quartz crystal of pure whitish feldspath. With increasing cooling of the stone, the horizontal pillars shrunk in cross-section and fissures occurred at an angle of 120 degrees, which usually formed 6-sided pillars.
Missouri Buttes, 5.5 mile (.6 km) north-west of Devils Tower, also consist of pillar-shaped phonolites of the same ages. Devil's Postpile National Monument in California and Giant's Causeway in Northern Ireland, are also pillar-shaped basalts, which are similar on the surface, but with pillars with a typical diametre of 0.61m.
The Devils Tower did not rise out of the scenery until the upper sediments were removed. Because of the wear and tear of the soft sandstone and slate, the tower's more resilient eruptive stone has withstood the erosive force. Thus the grey pillars of the Devils Tower emerged as an insulated earth above the countryside.
To get away from the bear, the women clambered onto a cliff, kneeled down and worshipped the Great Spirit to rescue them. When he heard their prayer, the Great Spirit let the rocks soar from the floor to the sky that the bear could not intruder.
Climbing had become too difficult and the teddybear had scratched the sides. These are the signs that appear on the Devils Tower pages today. A different story says that two Sioux cubs were wandering far away from their villages when Mato the Beast, a giant animal with talons the scale of tipis bars, discovered them and wanted to ate them for breakfasts.
As Mato tried to get up from all sides, he left enormous scratches on a giant cliff. He retired at today's bears butte just south of the Black Hills. Wanblee, the Major, was helping the guys off the rocks and back to their town.
Herbert A. Collins' picture is hanging above the chimney in the Devils Tower Visitors' Centre. During the last years the climb of the Devils Tower has gained more and more people. First known climb of Devils Tower took place on 4 July 1893 and is registered with William Rogers and Willard Ripley, the area' s own franchise.
This first climb was concluded after the construction of a step made of wood blocks drifted into fissures in the crags. Some of these crayons are still preserved and can be seen on the tower as you walk the 1.3 mile (2.1 km) Tower Trail along the Devils Tower National Monument.
Fritz Wiessner, who climbed the tower in 1937 with William P. House and Lawrence Coveney, is the most renowned man.
