The Winter of 1804-1805 was spent at Fort Mandan, on the Missouri River, sixteen hundred miles from its junction with the Mississippi. In the Spring the party, now thirty-two strong, pressed on up the Missouri, which now turned in a decidedly westward direction. Between the Little Missouri and the upper waters of the Missouri proper, game was found in very great quantities, this region having been famous in that respect until the present generation. One game animal with which white men had not been acquainted was now encountered,--the grizzly bear. Bears in the Middle West were, under ordinary circumstances, of no danger; these grizzlies of the upper Missouri were very bold and dangerous. Few Indians were encountered on the upper Missouri. Fall had come ere the party had reached the difficult portage from the Missouri to the Columbia; the distance from the Mississippi to the Falls of the Missouri, at the mouth of the Portage River, the point near which the land journey began, was 2,575 miles. The Portage to the Columbia was 340 miles in length. Having obtained horses from the Shoshones, the Indians on the portage, the explorers accomplished the hard journey through the Bitter Root Mountains. The strange white men were received not unkindly by the not less strange Indians of the great Columbia Valley, though it needed a bold demeanor, in some instances, to maintain the ground gained. Yet on the men went down the river and encamped for the Winter on the coast near Point Adams,--the end of a journey of over four thousand miles. Here the brave Captain Gray of Boston, thirteen years before, had discovered the mouth of the Columbia and given the river the name of his good ship. The Winter was spent hereabouts, the explorers suffering somewhat for lack of food until they learned to relish dog-flesh, the taste for which had to be acquired. By March, 1806, they were ready to pull up stakes and begin the long homeward journey.
