1965 South Park Buffalo.jpg
South Park PA: A Buffalo grazing in South Park.
The buffalos were brought to South Park (and North Park) in the late 1920s along with real Western Indians. The Indians were living in the park but it was short-lived; the North Park tribe were evicted because they were eating the buffalo and the South Park tribe left due to the cold weather. But the Bison / Buffalos remain.
