It was the deadliest day in Colorado history: November 29, 1864 – the Sand Creek Massacre. More than 230 people — mostly women, children and elders from the Arapaho and Cheyenne nations were killed near Eads in the Eastern Plains.
The City of Boulder is working with the Arapaho and Cheyenne tribes to recognize Boulder’s connection to the tragedy.
The city-owned open space northeast of Boulder, near 63rd Street and Andrus Road, is where Fort Chambers likely stood. The structure built of sod in the summer of 1864 was used to train a volunteer militia.
