Ben Cartwright finds out that Mark Burdette (Barry Sullivan) and Early Thorne (Leo Gordon) have been illegally slaughtering the antelope on the Paiute Indians' property, then selling the meat to the miners at an exorbitant price. To thwart the two poachers and protect the Indians' food supply, Ben offers to sell his own meat at a much lower price. Burdette and Thorne then hatch a scheme to foment a war between the Paiutes and the Cartwrights. First telecast on September 19, 1959, "The Sun Mountain Herd" (aka "Death on Sun Mountain") was written by Gene L. Coon and David Dortort, who based their teleplay on a true story. ~ Hal Erickson, Rovi
