Devils Tower is a blob of crystallized magma that intruded between two layers of sedimentary rocks, some 40 million years ago. Over time these layers eroded away, exposing the 400 m high tower.

The name is actually a wrong translation, there is a continuous endeaver to rename the tower to Bear Lodge which is more in line with the Indian naming and folklore.

 

In 1906  Teddy Roosefelt declared it a National Monument, the first in its sort.

 

Daredevil George Hopkins parachuted down on the summit in 1941, but his  provisions to scale down failed and he had to spent 6 cold days on the windy top.

 

Presently the tower is a popular climbing object, much to the chagrin of the local tribes that regard the tower sacred.

 

In August 1992 we stopped by Devils Tower.
