Well done and informative center. Information on the rivers as well as Sitting Bull (without an opinionated presentation, that was refreshing). Exhibits and video for $5; free for veterans. Ticket also good for Fort Buford. Walkway to view the confluence. Lots of mosquitoes. Only negative was person manning the desk as when asked how to get to viewing area to see the confluence, he replied he didnt know . . . . Definitely worthwhile to take the timeto visit this out of the way spot and visualize the Native Americans and the Lewis and Clark Expedition passing through. read more
