Throughout the first half of the 1860s the Ute were known for raids in the Big Thompson Valley, where present-day Loveland, CO. is located.
Northern Colorado has been home to many cultures and people, including the Arapaho, and a well-known member of the nation named “Chief Friday”.
Geological surveyor F.V. Hayden encountered Friday in 1859 or 1860 in what is now the State of Wyoming. But by 1861 Friday and his band were relocated on the Cache la Poudre River, occasionally traveling to the Big Thompson Valley as well.
In July 1862 the Friday band was camped on the north side of the Poudre River, opposite the F.W. Sherwood Ranch. In June of the following year Friday and his group, and another band of Arapaho under Many Whips, were seen in the Poudre Valley. By August of 1863 Friday was seen near Fort Laramie, to sign a treaty along with Northern Arapaho chiefs Black Bear and Roman Nose.
The agreement stipulated that the signers would abide by any treaty made by their people, the Northern Arapahoe. Given the fact they had made no treaties to that time the agreement was null and void.
