Devils Tower is a monolithic rock formation in the Black Hills of Wyoming. It is 264 m tall, 2.1 km in circumference, and covers 540 ha. The tower is made of igneous rock that was formed about 200 million years ago.

The formation of Devils Tower is thought to have been caused by a volcanic eruption. The eruption caused a magma chamber to form underground. The magma chamber eventually cooled and solidified, forming the tower. The tower’s unique shape is thought to have been caused by erosion. The wind and rain have eroded away the softer rock around the tower, leaving the harder rock behind.

Devils Tower is a popular tourist destination. It is also a sacred site for many Native American tribes. The Lakota, Kiowa, and Cheyenne tribes all have legends about the tower. The Lakota believe that the tower was created when a bear tried to climb to the top of the mountain to escape from a group of young boys. The bear’s claws left the distinctive grooves in the side of the tower.

Devils Tower was designated a national monument in 1906 by President Theodore Roosevelt. It is managed by the National Park Service. Climbing is allowed on Devils Tower, but there are strict regulations in place to protect the tower. Devils Tower is a popular spot for rock climbers. The first person to climb to the top of the tower was William Rogers in 1893. Devils Tower has been featured in several movies, including Close Encounters of the Third Kind.
