Devil's Tower is a spectacular geologic formation that protrudes out of the surrounding rolling prairie. It rises dramatically 1,267 feet (386 m) above the terrain and the summit is 5,114 feet (1,559 m) above sea level. It is located near the town of Hulett in Crook County, in northeast Wyoming. Hundreds of parallel cracks make it one of the most popular climbing areas in N. America.
Geologically, it is an igneous intrusion (technically, called a "laccolith") that protrudes out of the surrounding sedimentary rock layers. Geologists believe that about 65 million years ago, during the Paleogene Period, the Rocky Mountains and the Black Hills were uplifted. Magma rose through the crust, intruding into the existing sedimentary rock layers.
Devils Tower was the first declared United States National Monument, established on September 24, 1906, by President Theodore Roosevelt.
The site is considered Sacred to the Lakota and other tribes that have a connection to the area.
It was featured in the 1977 movie "Close Encounters of the Third Kind". #igneous #Rock_climbing #wyoming
