Gov. John Hickenlooper has approved a 640-acre land transfer to expand the historical preservation of the Sand Creek Massacre site.
The Denver Post reports the announcement came on the 151st anniversary of the deadly event near Eads where about 200 people — mostly women, children and the elderly — were killed when U.S. Army soldiers ambushed the camp of Cheyenne and Arapaho chiefs on Nov. 29, 1864.
The 640 acres designated for expansion are next to the current historic site. Superintendent of the Sand Creek Massacre National Historic Site, Alexa Roberts, says the land is where soldiers prepared before the attack.
