January 30, 1971 James Arness of Gunsmoke

Star James Arness and the rest of the Gunsmoke cast and crew journey to Custer, SD, for an episode that involves Sioux Indians, a blizzard and a 19th-century locomotive.

"Arness," TV Guide says, "enjoyed chatting with the Indians but didn't enjoy swimming [with his horse], as the plot required, in a fast, icy river. The horse's feelings went unrecorded."
