But the true name is Cheyenne, from the Indians who bear that title.

The stream rises in the region called the Black Mountains by Lewis and Clark, on account of the great quantity of dark cedar and pine trees that covered the hills.

This locality is now known as the Black Hills, in the midst of which is the famous mining district of Deadwood.

In these mountains, according to Lewis and Clark, were to be found "great quantities of goats, white bear, prairie cocks, and a species of animal which resembled a small elk, with large circular horns." By the "white bear" the reader must understand that the grizzly bear is meant.

Although this animal, which was first discovered and described by Lewis and Clark, is commonly referred to in the earlier pages of the journal as "white," the error naturally came from a desire to distinguish it from the black and the cinnamon-colored bears.
