Indiana Topography

The most important feature of Indiana is its three types of physical geographical regions. The first most important is the great lake plains situated in the northern part of Indiana. This region has highly fertile soil formed by the retreating action of glaciers at the end of the ice age. The great plain region also has many sand dunes situated along the region of Lake Michigan. These great lake plains are so named as they are located along the great lakes Ohio, Wisconsin and Illinois. The second type of geographical region is the till plains which are located in the southern side and extends towards the Ohio River. This region contains many low hills and valleys. The soil of this region is also highly fertile and thus very much suitable for fertilization. The third type of geographical region is the Southern Plains and Lowlands situated southwards to the till plains. The highest peak of Indiana is the Hoosier Hill situated at the Franklin Town which is about 1,257 feet above the sea level.

Indiana has an extensive river system. The major rivers are the Wabash River which flows through the north central region of Indiana and finally drains into the Ohio River present in the southern side are the Maumee River that flows into the northern region and the Kankakee River, The Ohio River, Tippecanoe River and the White Water River. The lowest point in the Indiana is at the place where the Wabash River drains into the Ohio River which is present just 320 feet above the sea level.

Indiana has around 400 lakes; the most important among these are the Lake Michigan, Lake Wawasee, Lake Shafer, Lake Maxinkuckee and the Monroe Lake. The land of Indiana has an underlying layer of rocks which is believed to have formed as a result of the submersion of the land that occurred thousands of years ago. .
The geographical location of Indiana within the continent plays a major role in its climatic conditions. Due to its position adjacent to the Gulf of Mexico, warm and moist air is passed towards it by the southern wind. The jet stream that arise from the western and central Canada helps in passing the polar continental air to the state which often collides with warm moist air brought by the southern wind.
