A crucial part of preserving America’s wilderness is the preservation of the historic events that occurred in those regions. The National Park Service’s preservation of the Sand Creek Massacre National Historic Site in Colorado is a great example of this. The site commemorates the November 29, 1864 attack on a village of about 700 Southern Cheyenne and Arapaho people along Sand Creek in southeastern Colorado Territory, about 170 miles southeast of Denver. At dawn, approximately 675 soldiers of the 1st and 3rd Regiments, Colorado Volunteer (U.S.) Cavalry, killed more than 230 Cheyenne and Arapaho over the course of seven hours. Colonel John M. Chivington led an unprovoked surprise attack on a peaceful camp using small arms and howitzer fire to kill as many Cheyenne and Arapaho, mostly women and children, as possible. The brutal attack is remembered at the historic site, where visitors can learn about what happened, why it mattered, and the crucial efforts towards peace that followed. To commemorate the paths less traveled in national recreation areas (these places receive far fewer visitors than National Parks), Anderson Design Group poster artists hand-rendered an original illustration in the fashion of vintage poster art and travel art. This retro design and original National Park art is available as a poster, print, canvas, mini canvas, metal sign, notecard, or postcard.
