Lake Wawasee (Indiana's largest natural lake),
The smallest state west of the Appalachian Mountains
(not counting Hawaii), the landscape of Indiana is
influenced by three main land regions; the Great Lakes Plains in the north, the Till Plains in central
Indiana and the Southern Plains and Lowlands in the south, the hilliest section of the state.
Great Lakes Plains: The Great Lakes Plains is a fertile lowland that runs along the Great Lakes
from Wisconsin through Illinois and Indiana to Ohio. Along
the land is characterized by large sand dunes. To the south of the sand dunes the rich black soil is perfect
for Indiana farmers. There are many small lakes and low hills south of the sand dunes. This area is sometimes
referred to as the Northern Lake and Moraine Region. Moraines are low hills of earth and rocks left behind by
melting glaciers at the end of the ice age.
Till Plains: The Till Plains lie to the south of the Great Lakes Plains and run through the center
of Indiana. The broad, fertile Till Plains in Indian are a part of the great Midwestern Corn Belt.
The landscape of the Till Plains is characterized by low hills and valleys. The highest point in Indiana,
Hoosier Hill, is located in Franklin Township in the east.
Southern Plains and Lowlands: South of the Till Plains lie the Southern Plains and Lowlands. Ice age
glaciers did not advance into this southerly section of Indiana so this area is the hilliest part of the state.
"Knobs" are steep hills and this land is characterized by a series of knobs divided by lowlands. It is in this
region of Indiana where several caverns, including
and Wyandotte caves, have been carved in the limestone by underground streams.
