This November 29 marks the 150th year since the Sand Creek Massacre was carried out. On that fateful day, regiments of Colorado (U.S.) Volunteer Cavalry attacked a peaceful Cheyenne and Arapaho village along the Big Sandy Creek.

Those who lost their lives will be remembered as part of the commemoration activities planned at the Sand Creek Massacre National Historic Site throughout the day.
