November 29, 2022 marks the 158th anniversary of the Sand Creek Massacre, when U.S. troops attacked a peaceful camp of Cheyenne and Arapaho people. In addition to remembering the more than 230 people murdered that day, the anniversary compels us to face this history with raw honesty.  

Just ten days ago, 150 members of the Cheyenne and Arapaho Tribes joined History Colorado to reflect on the massacre and commemorate the opening of the exhibition that we co-developed through many years of government-to-government consultations. 

Over the coming year, History Colorado and our Tribal partners will offer more educational opportunities around this history. In December and January, our education team will be finalizing our field trip program to complement the Sand Creek Massacre exhibition. On April 19, Tribal representatives along with Dr. Alexa Roberts and Dr. Ari Kelman will discuss the establishment of the Sand Creek Massacre National Historic Site. We’re sharing additional resources designed to enable deeper learning about the massacre in The Colorado Magazine. And a Lost Highways podcast about the massacre will debut in spring 2023. We encourage you to keep learning and keep questioning.  

The Sand Creek Massacre 

The Betrayal that Changed Cheyenne and Arapaho People Forever exhibition is open daily at the History Colorado Center and is included in a general admission ticket. The National Historic Site is open Thursday through Monday, and its website is, of course, 24/7. And we are always adding new things to our own ever-expanding website.
