TheIndiana Uplands or theHoosier Uplands are a geographical region in south-centralIndiana. On a topographical map the Indiana Uplands begin slightly north of the city ofMartinsville, Indiana and continue south to theOhio River. The description of the region inspired the name ofUpland Brewing Company. The region's approximate boundaries areInterstate 65 to the east andU.S. Route 231 to the west.[1] The Uplands are characterized by terrain varying from rolling hills to cliffs, sharp rugged hills and valleys. Nearly all of these hills are composed of sandstone, limestone, and siltstone from West to east. The siltstone hills are the most rugged followed by the sandstone while the limestone are the smoothest. This is contrast to the Tipton Till Plain immediately to the north in central Indiana, which features flat to gently rolling landscape.[2][3] Interstates64 and69 pass through this rugged section of the state with sections of both cut deep into the rock and others towering over the treetops. Overall, the Indiana Uplands have the same basic characteristics of thePennyrile Region and theHighland Rim and are the northernmost extent of the range.
The Indiana Uplands include the following ecoregions:[1][4]
