General Overview of Trail
Illinois, the Prairie State, is mostly a land that glaciers have smoothed out and left with rich deposits of soil that produce abundant crops. Under that soil lies the largest coal reserves in the nation, but it is manufacturing that provides the most employment.
The ADT's two routes through Illinois are quite different in character. The Northern Midwest Route is across land that is flat to slightly undulating mostly along two canals. By contrast, the Southern Midwest Route goes through very hilly country, untouched by glaciers. This area is known as the Illinois Ozarks or the Shawnee Hills and geologically remains much as it has been for eons.
