Illinois State Map- Our Illinois map beautifully displays the delicate landscape. From Lake Michigan to the Ohio and Mississippi Rivers, the valleys, plains, rivers, and prairies are exquisitely mapped in shades of greens and light browns. Elevations are represented by color, and this, in combination with our relief shading technique, gives the map a 3-dimensional look. 33 inch by 55 inch in size. 1:500,000 Scale.
