Poison Springs Battleground State Park is an Arkansas state park located southeast of Bluff City. It commemorates the Battle of Poison Spring in the American Civil War, which was part of the 1864 Camden Expedition, an element of a Union Army initiative to gain control of Shreveport, Louisiana, and get a foothold in Texas.

Milky Way & night sky
From Poison Springs Battleground State Park, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 6.0 hours on a moonless night), and the core peaks around 27° above the southern horizon. Our light-pollution model puts the sky at about Bortle 2 (typical truly dark site), which is excellent for astrophotography.
