The site is located three miles east of Baldwin City Kansas and was the location of the first battle in Kansas between pro-slavery and anti-slavery forces on June 2, 1856. The battleground covers 20.27 acres of land which includes Black Jack Creek, prairie, and woodland. The nominated site includes Black Jack Park, Ivan Boyd Prairie Reserve, and the Robert Hall Pearson Memorial Park. Black Jack Park was established in 1940 as a roadside park to commemorate the battleground located a short distance away from the site.Two years before the park was built, a memorial for the battlefield was moved to the site. A large log cabin was later built in 1969. Two additional monuments were added in 1940 and 1984 dedicated to the Battle of Black Jack and the neighboring town.

Ivan Boyd Prairie Reserve is a strip of uncultivated land which contains 125 species of native grasses and wildflowers. The Santa Fe Trail wagon ruts are visible here and there is a small footbridge which spans Black Jack Creek. The Robert Hall Pearson Memorial Park is 0.27 acres of woodland, donated to Douglas County in 1970. Wooden signs recognize the 48 men who fought in the battle and an additional granite marker was moved to the site to commemorate the Battle of Black Jack. Currently, the Black Jack Trust is working on obtaining funding to build a visitor center at the historic site, create walking trails throughout the site, and restore the native prairie grasses on the site.
