Devil’s Tower

Sunday, January 4th, 2009

If you ever seen the movie Close Encounters of the Third Kind then you’ve seen the Devils Tower. This distinctive mountain landmark is hard to miss.

It became famous when Richard Dreyfuss began having visions of the Devils Tower with its flat top and ridged sides. Soon after having the visions he constructs a crew sculpture in his mashed potatoes. Needless to say his family is alarmed. He becomes more and more obsessed with the mountain. First he makes paintings of it, then he goes off the deep end. When he brings in piles of dirt from the yard to create a scale replica in his living room, his wife and kids leave him. It’s a very famous scene in the movie.

Eventually Richard’s character travels to Wyoming to see the real Devils Tower. Despite warnings from the military to stay away, he sneaks up to the mountain. There he sees an amazing spectacle. Aliens land after communicating with humans using a giant organ. Many people, abducted long ago, come off the ship. Richard’s character is amongst those who choose to travel with the aliens back to their home planet. Given the way Hollywood makes sequels, it’s surprising this open ending didn’t spawn a second movie. It still might. Later versions shown on television and released on DVD included scenes inside the ship. But these weren’t very well done.

Back to the real Devils Tower. It’s located in Wyoming. It’s a monolithic igneous intrusion, otherwise known as a volcanic neck. This is also known as a lava neck. It forms when magma flows out of a volcanic vent. It’s generally the sign of an active volcano. It’s not certain that this formation is such a plug. But many geologists believe it is.

The Indians have a legend about how Devils Tower was formed. Some Indian sisters were walking in the wilderness, picking flowers, when they came upon some bears. The bears chased them. The Great Spirit helped the girls by raising up the land upon which they stood. The Bears would not give up. They tried to climb up to the girls but as they neared the top slid back down. Their claws left the indentations in the side of the structure.

Another legend, this one told by the Sioux Indians, was of two boys wandering far from their village. A giant bear called Mato came upon them. It had claws the size of tepees, and it wanted to eat the boys for breakfast. The boys prayed to the creator to help them. He did, raising the ground beneath them. Just as with the stories involving the girls, and this one the giant bear tried to get at them from all sides but could not. Its huge claw marks remain.

Whether fantastic tales of giant bears or friendly aliens the Devils Tower is a great place to visit.
