Ranching Facts

Temple Grandin got down inside the cattle chutes at Arizona feedlots in the early 1970s to see what the cattle saw, and people thought she was crazy. She found what made them stop: a shadow, a hanging rope, a coat on the fence. Her curved chutes with solid sides now work on ranches and feedlots worldwide. At 79, she still teaches at Colorado State.

A Texas ranch wife helped save the American bison. By 1878, hide hunters had nearly wiped out the southern herd. Mary Ann Goodnight urged her husband Charles to rescue a few orphaned calves. Those calves started one of five herds that seeded nearly every bison in North America. Their descendants still roam Caprock Canyons State Park, right through the campground.
