2 time zones
Also, why does South Dakota have two time zones? The Northern Pacific continued to make the time change between Central and Mountain time at Mandan. Which is pretty much the same boundaries as the current time zone line. And I believe that is the reason Southwestern ND to this day is in the Mountain Time Zone and the rest of the state is in the Central Time Zone.
