Native Americans hunted huge herds of bison on the Plains thousands of years before European Americans settled there. In the 1870s, cattle ranchers spread into the Plains, railroads were built, and millions of bison were slaughtered. Conservation efforts have brought the bison back from near extinction. A bison shown against the sun on the horizon is the design for this stamp, issued in several formats.
