Thought I'd better add this I had a typo while I was writting my first post. Roosevelt did not make it a park it was congress.

Hot Springs is the smallest and oldest of the parks in the National Park System, dating back to 1832, when Congress established - 40 years ahead of Yellowstone - the first federally protected area in the nation's history. Hot Springs Reservation - which was renamed Hot Springs National Park in 1921 - originally was created by Congress to protect the 47 naturally flowing thermal springs on the southwestern slope of Hot Springs Mountain.

I just spent a week in Hot Springs Ark. last week. You forgot to mention that Hernando De Soto was shown the Hot Springs (Valley of the Vapors)by the Native Americans in the area when he was stomping around thorough North America in 1541 looking for gold. Also Roosevelt made it the Very first Nation Park in the Country, years before Yellowstone and Yosemite. He took the Rough Riders to Hot Springs in about 1896.
The State Capital was moved to Hot Springs during part the Civil War out of fear that they would be attacked in Little Rock, and there was an Army and Navy medical hospital right off bathhouse row during the Civil War. Al Capone, and Babe Ruth frequented Hot Springs as well. I for one would be suprised if Bath House row wasn't on the historical list.
