The origins of the park was in 1922 with the donation of land on Shoal Creek for a city park. In the 1930s and '40s the Works Progressive Administration (WPA) built Schermerhorn Park's stone terracing, walls and other structures. Schermerhorn Park is home to some of the rarest animals in Kansas. Schermerhorn Cave and the spring that flows from it are the home to grotto salamanders, dark-sided salamanders, cave salamanders, and the graybelly salamander. Rare species of mussels, such as Neosho Mucket and Rabbitsfoot can be found in the adjacent Shoal Creek. Although Schermerhorn cave is nearly a 1/2 mile long, the entrance is blocked with a steel gate to protect the habitat. Only the twilight zone of the cave can be seen from a platform at its entrance. The park is part of the 55 square mile section of the "Ozarks of Kansas" formed by the geologic feature, the Ozark Plateau, that is in the very southeast corner of Kansas. This region with its caves, sinking streams, and sinkholes is made of Mississippian limestone which was deposited over 300 million years ago.
