Dr. Allen assigns the Alleghany Mountains as the general eastern boundary of the range of the buffalo, although explaining that it frequently passed beyond that range, and showing conclusively that it occurred in the western portions of New York, Pennsylvania, Virginia, North and South Carolina and Georgia. Mr. Hornaday cites some evidence to show that it occurred in the District of Columbia, and quotes Francis Moore, in his “Voyage to Georgia,” to prove that there, at least, buffalo were found close to the salt water.
While Dr. Allen gives the Tennessee River as the southern boundary of the buffalo’s range, west of the Alleghanies and east of the Mississippi River, Mr. Hornaday quotes a number of references to show that it occurred in some numbers in what is now the state of Mississippi, and gives a tradition of the Choctaws, narrated by Clayborne, in regard to the disappearance of the species from that section. This tradition is to the effect that during the early part of the eighteenth century a great drought occurred there by which the whole country was dried up. For three years not a drop of rain fell. Large streams went dry, and the forest trees all died. Up to that time, it is said, elk and buffalo had been numerous there, but during this drought these animals crossed the Mississippi River and never returned.
In the eastern portion of its range, the Great Lakes formed a barrier on the north which the buffalo did not pass; but from western New York westward, it was found in numbers along the southern shores of these lakes, and in the territory now Ohio, Indiana, Illinois, Michigan, and Wisconsin. Audubon tells us that in the first years of the nineteenth century there were buffalo in Kentucky, but declares that about 1810, or soon after, they all disappeared. This disappearance was due chiefly to their actual destruction by white men and by Indians, and not, as is commonly stated, to the retiring of the great herds before the advance of settlement and civilization. It seems that the last buffalo were killed east of the Mississippi River about the year 1820, although it may be that in Wisconsin and Minnesota they lasted somewhat longer.
West of the Great Lakes, and turning sharply northward so as to run nearly northwest, the eastern border of the buffalo’s range west of the Mississippi was a line running very near the western extremity of Lake Superior, up through the Lake of the Woods, west of Lake Winnipeg, and thence northward to and beyond the Great Slave Lake. There this border line turned to the west, and then sharply to the south, and meeting the Rocky Mountains not far from where Peace River leaves them, followed the range south, about to the 49th parallel; and then turning southwestwardly and including Idaho, a part of eastern Oregon, the northeast corner of Nevada, the greater portion of Utah, and most of New Mexico, the line passed down south well into Mexico, turning eastwardly just north of the 25th parallel of latitude, and running north to the coast, which it followed around again to the mouth of the Mississippi.
As it has been known in our day, the buffalo in the southern portion of its range was a trans-Missouri animal. North of the parallel of 45 degrees it was found in equal numbers on both sides of the Missouri River, and in its northern extension reached, and possibly even to-day reaches, north to Great Slave Lake; for, as already stated, the only considerable band of wild buffalo to-day is the wood bison of the north, estimated to number four hundred or five hundred.
Besides the boundaries thus set forth, it is probable that in early days there was a considerable extension of the buffalo’s range northward and westward, into portions of what is now Alaska. Certain it is that in that territory buffalo remains have been found in great numbers. Some of these skulls belong to species long extinct, and much larger than the American bison; but, on the other hand, there are many which are closely similar to that species.
The range of the buffalo to the west of the Rocky Mountains began to contract not very long after the narrowing of its range on the east. The earlier explorers in the West, from Pike downward, report buffalo in abundance. Yet, as already stated, the westernmost point at which their remains have been found is among the foot-hills of the eastern side of the Blue Mountains of Oregon. In 1836, it is reported, buffalo were abundant in Salt Lake Valley, but there nearly all were soon afterward destroyed by deep snows, which covered the ground for a long period of time. This corresponds well with statements made to me by John Robinson, better known in early days as Uncle Jack Robinson, one of the old-time trappers, who died between 1870 and 1880. In 1870 he told me that the buffalo on the tributaries of the Green River and on the Laramie Plains had all perished nearly forty years before, during a winter when very deep snows fell, followed by a thaw and subsequent cold, which crusted the snow so that the buffalo could not get through it, and starved to death. This statement was confirmed by the small number of remains, most of them extremely old and weathered, which we found in this region at that time. On the other hand, on upper tributaries of the Green River buffalo were found much later, and it is possible that these may have been animals which wintered in narrow valleys of the mountains, where, during this deep snow, food was accessible. Fremont states that in the spring of 1824 buffalo were abundant as far west as Fort Hall, while Bonneville reported them in extraordinary abundance in the Bear River Valley.
The mere fact that buffalo were not seen by an explorer who passed through any given territory does not necessarily show that they did not range in that country. I have travelled for months through a buffalo range without seeing buffalo or any evidence of their very recent presence, yet the signs found showed conclusively that a short time before they had been there in vast numbers. It would have been perfectly possible for two honest reports, made a few months or years apart by explorers who were not prairie men, absolutely to contradict each other.
Although the buffalo disappeared from the country west of the Green River, and even from the Laramie Plains, a long time ago, it lingered much later on tributaries of the Platte River further to the northward. There were buffalo on the Sweetwater and its tributaries between 1870 and 1880, and on certain other tributaries of the North Platte River between 1880 and 1890. About this same time there was a small band ranging in what is called the Red Desert Country, south of what is now the National Park. But the last of these disappeared about 1890.
