RELIEF MAP SHOWING THE EARLY DISTRIBUTION OF AMERICAN BISON. 



Prepared and placed in the American Museum of Natural History under the direction of 

 The American Bison Society. 



The dots on the map above represent the limit of the bison's range over North America 

 about one hundred years ago. In 1850, at the time the mining industries in California were 

 developing, "buffalo" were still very abundant, and were seen in countless numbers by those 

 traveling the plains. In the year 1875, they occupied only a relatively small portion of the 

 country. The northern herd occupied the eastern foothills of the Rocky Mountains and the 

 sparsely settled plains of the northwest, and the southern herd roamed over the country that 

 now comprises part of the states of Nebraska, Kansas, Colorado, Texas and Oklahoma.
