Chapter 07: Removal & Niwot's Founding

After the Sand Creek Massacre, the federal government formally repudiated the attack in the 1865 Treaty of the Little Arkansas, yet never paid the reparations it promised to the survivors. Two years later, the Medicine Lodge Treaty forced the Southern Arapaho and Southern Cheyenne to cede their remaining lands in Colorado and relocate to a reservation in Indian Territory. During the 1870s, as military campaigns pushed the last remaining Arapaho and Cheyenne families south to the new reservation, white settlers founded the town of Niwot, naming it for the Arapaho chief whose people had been permanently driven from the valley.

In March 1875, Porter M. Hinman helped found the new town of Niwot, which settlers named in honor of Southern Arapaho Chief Nowoo3 ("Niwot," Left Hand). Eleven years earlier, Hinman served in Company D of the Third Colorado Cavalry that participated in the 1864 Sand Creek Massacre, where Chief Nowoo3 was mortally wounded.
