From Lake Michigan in the north to the Ohio River, Indiana is a state of subtle elevation changes marked by small lakes, low sandy hills, "knobs" or steeper hills, and limestone caves in the south created by underground streams. Elevations are represented by color, and this, in combination with our relief shading technique, gives the map a 3-dimensional look. 29 inch by 44 inch in size. 1:500,000 Scale.
