"Cooke...follows Glass minutely through all the adventurous way up the Missouri River...toward the supposed rendezvous of Henry's trappers." -James Bridger, Trapper, Frontiersman, Scout and Guide (1925)
Hugh Glass (c. 1780–1833) was an American fur trapper and frontiersman noted for his exploits in the American West during the first third of the 19th century. Glass was born in Pennsylvania, to Irish parents. He was an explorer of the watershed of the Upper Missouri River in present day North Dakota, South Dakota and Montana. Glass was famed, most of all, as a frontier folk hero for his legendary cross-country trek after being mauled by a grizzly bear. Glass' most famous adventure began in 1822, when he responded to an advertisement in the Missouri Gazette and Public Adviser, placed by General William Ashley, which called for a corps of 100 men to "ascend the river Missouri" as part of a fur trading venture. These men would later be known as Ashley's Hundred.
