In 1851, 10,000 Plains Indians from 10 tribes met government officials near Horse Creek to form a treaty. Never in recorded history had so many gathered at one spot on the Plains. From the government’s perspective, the treaty’s purpose was to ensure safe passage for people using the Oregon Trail and to stop intertribal warfare.
The government broke the treaty almost immediately. The Horse Creek Treaty Marker is 3 1/2 miles west of Morrill on Highway 26. Every July, Morrill’s Horse Creek Rendezvous commemorates the event.
