Battle of the Little Bighorn known today as Custer Hill. At least 28 bodies (the most common number associated with burial witness testimony), including that of scout Mitch Bouyer, were discovered in or near that gulch, their deaths possibly the battle's final actions. Although the marker for Mitch Bouyer has been accounted for as being accurate through archaeological and forensic testing, it is some 65 yards away from Deep Ravine. Other archaeological explorations done in Deep Ravine have found no human remains associated with the battle. According to Indian accounts, about 40 men made a desperate stand around Custer on Custer Hill, delivering volley fire.
