By Richard L. CarrThe major reason for the 1902 Roundup was to clear the trespassing cattle from the reservation. Indian agent Mr. McChesney aggressively pursued the legal paperwork of the Fort Laramie Treaty; supported by the US congressional action and President Roosevelt. Between thirteen and sixteen reservation roundup wagons headed by Wagon-boss Jack Wipple, plus 1,000 cowboys, cooks, and Reps with nearly 10,000 horses, met  with the herds gathering them east and south of Pine Ridge and Rosebud Reservations in the waterways and grasslands of the Keya Paha , Niobrara and the Missouri River. This is believed to be the largest roundup and cattle camp ever known on any range. Was the roundup was completed  a five-wire perimeter fence was constructed just north and south of the Big White River. Book contains a detailed map of round up.
