Williston Zoo? (transfer, park, map)

[NDak15]

I was on the website for Theodore Roosevelt National Park and on the section talking about the bison round ups they had a map showing where excess bison had gone. It was between 1956 and I think 2016. One of the recipients was Williston Zoo. When did Williston have a zoo? Does anyone know the history of that? I've only been in North Dakota four years so still learning a bit.
