Rick Rosner watches Antiques Roadshow and encounters a letter from the widow of General George Armstrong Custer. Rick Rosner recounts Custer’s role in the Indian Wars and the 1876 Little Bighorn defeat by Lakota, Northern Cheyenne, and Arapaho. He corrects a Boulder myth: Sand Creek’s massacre occurred near Eads, led by John Chivington, killing 150–230 women and children, after Fort Laramie and Fort Wise treaty betrayals. He links atrocities to Canada’s residential schools affecting 150,000 Indigenous children, recalls Phoenix Indian School, and notes the still close WWII memory. Future harms may be economic, political, or technological.
