what landforms are found mostly in the southern part of indiana
Geography of Indiana Southern Indiana is a mixture of farmland, forest and very hilly areas, especially near Louisville and in the south central lime hills areas, stretching from the Ohio River to as far north as Greencastle, to the wide, flat valleys along the Wabash and Ohio rivers. The Hoosier National Forest is a 200,000-acre (810 km2) nature preserve in south central Indiana. Southern Indiana's topography is more varied than that in the north and generally contains more hills and geographic variation than the northern portion, such as the "Knobs," a series of 1,000 ft (300 m) hills that run parallel to the Ohio River in south-central Indiana. The largely flat and flood-prone bottomlands of Indiana, where the Wabash, White, and Ohio Rivers converge, hosts numerous plant and animal species normally found in the Lower Mississippi and Gulf Coast region of the United States.[15] Brown County is well known for its hills covered with colorful autumn foliage, the former home of T. C. Steele, and Nashville, the county seat and shopping destination. Harrison and Crawford Counties boast three of the state's most popular commercial caves at Wyandotte, Marengo, and Squire Boone Caverns.
