Region of Indiana, United States
Northern Indiana is a geographic and cultural region that generally comprises the northern third of the U.S. state of Indiana and borders the states of Illinois to the west, Michigan to the north, and Ohio to the east. Spanning the state's northernmost 26 counties, its main population centers include Northwest Indiana, Michiana, and the Fort Wayne metropolitan area. Northern Indiana's physical geography was significantly shaped during Wisconsin glaciation, resulting in a till plain ranging from flat to gently rolling terrain, especially in the Wabash Valley. The region experiences a humid continental climate, supporting temperate deciduous forest, tallgrass prairie, and wetland ecosystems. In addition to Lake Michigan, more than 300 kettle lakes are located in the region, including the state's largest natural lake and deepest natural lake. Wikipedia
