December 7, 1804
We were informed by a chief that great numbers of buffalo were on the hills near us. Captain Lewis with a party went out and killed eleven… the weather so excessive cold and wolves plenty, we only saved five of them.
This morning a boy of thirteen years of age came to the fort with his feet frozed, having stayed out all night without fire, with no other covering than a small robe… the mercury stood at 72 below the freezing point. Several others stayed out all night not in the least hurt… Customs and habits of those people has anured them to bear more cold than I thought it possible for man to endure.
