Only one Southern Plains bison herd was established in Texas. A remnant of the last of this relict herd had been saved in 1876. "Molly" Goodnight had encouraged her rancher husband, Charles Goodnight, to save some of the last bison which were taking refuge in the Texas Panhandle. By saving these few Plains bison, she was able to establish a buffalo herd near the Palo Duro Canyon. This herd peaked at 250 in 1933. Bison of this herd were introduced into the Yellowstone National Park in 1902 and into the larger zoos and ranches throughout the nation. A herd of around 80 of these animals lives in the Caprock Canyons State Park near Quitaque, Texas, located about 50 miles northeast of Plainview, Texas.
