Note 116 — {147} CHAPTER VIII {VI}

The name "Black Hills," which is now associated with the mountains of southwestern South Dakota, has also been applied somewhat indefinitely to hills in Nebraska, Wyoming, and Colorado. Lewis and Clark's map places hills so named along the eastern side of the North Platte, running well into Nebraska. The name is sometimes given to the hills enclosed by the circular course of the North Platte, in southeastern Wyoming; while Frémont (1842) applies it to the hills through which Cache la Poudre River cuts its way to the South Platte.—Ed.
