Speaker Series:
Silas Soule: Witness at Sand Creek

July 25, 2026

5:00–7:30 PM

National Western Center
Stockyards Event Center 
Directions

Free Admission

Sand Creek Massacre Foundation and Rocky Mountain Land Library are pleased to present a panel discussion on the legacy of Captain Silas Soule, with author Nancy Niero; Soule family descendant Byron Strom; Sand Creek descendant Chris Tall Bear; and journalist Kevin Simpson. 

Captain Silas Soule is remembered for refusing to fire on the peaceful encampment of Cheyenne and Arapaho people during the 1864 Sand Creek Massacre. His courage that day and his testimony after the event saved countless lives and led to the federal government's acknowledgement of the attack as a massacre.

Our panelists discuss his legacy and relevance today.

A book signing with Nancy Niero, author of Witness at Sand Creek: The Life and Letters of Silas Soule will follow the discussion.

This event is made possible with the generous support of the Rocky Mountain Land Library, the National Western Center, and the Boulder Bookstore.

Join us to hear Cheyenne author Tommy Orange talk about his family’s connection to Sand Creek and his 2024 book, Wandering Stars.

“Following its unforgettable characters through almost two centuries of history, from the horrors of the Sand Creek Massacre of 1865 to the aftermath of a mass shooting in the early 21st century, Wandering Stars is an indelible novel of America’s war on its own people”. From here

Tommy Orange received a BS (2004) from Expression College and an MFA (2016) from the Institute of American Indian Arts (IAIA). He is an enrolled member of the Cheyenne and Arapaho Tribes of Oklahoma. Orange currently serves as a faculty mentor at IAIA’s Low-Residency MFA in Creative Writing program.

Screening: Only the Earth and the Mountains

March 10, 2022

6:00 pm

Hosted on Zoom

Join us for an online screening of documentary, Only the Earth and the Mountains, followed by a panel discussion with filmmaker Elleni Sclavenitis and Conrad Fisher, Dr. Henrietta Mann, and Ryan Ortiz.

“Only the Earth and the Mountains interrogates the narrative of settler colonialism in the American West by white pioneers and its implications to society today by examining the repercussions of the Sand Creek Massacre, in which more than 200 Cheyenne and Arapaho people were murdered by U.S. Cavalry troops on November 29, 1864. In speaking to the survivors’ descendants, it becomes clear that this event is a living, perpetual loss—one that should not be forgotten.” You can learn more about Elleni and her work at www.sclavenitis.com

This event will be moderated by Dr Alexa Roberts, Sand Creek Massacre Foundation Board of Directors. Learn more about our panelists below.
