I realized after writing the first comment that it is updated in the description segment but the map still labels it as Shannon. I’m guessing some people will still call it Shannon and it really doesn’t matter so if nothing changes because of this I’m ok with that. Really I’m just bored and I think its fun to leave comments on random things like this. Hope you have a good day whoever is reading this
Shannon county changed its name to Oglala Lakota County in May of 2015.
