The Black Hills
And it was so. The great adventure of the Kiowas was a going forth into the heart of the continent. They began a long migration from the headwaters of the Yellowstone River eastward to the Black Hills and south to the Wichita Mountains.
A dark mist lay over the Black Hills, and the land was like iron. At the top of a ridge I caught sight of Devil's Tower upthrust against the gray sky as if in the birth of time the core of the earth had broken through its crust and the motion of the world was begun. There are things in nature that engender an awful quiet in the heart of man; Devil's Tower is one of them.
