Iowa 1969 Shaded Relief Map

We created this map with the illusion of 3D by applying Digital Elevation Data and meticulously adding shaded relief to the landscape of the original 1969 Iowa Geological map. The shading is printed on the paper and not a result of the map protruding from the surface. Please Note: Text on the map can be difficult to read due to the small font size and the age of the map. In areas where the relief shading covers the text, the underlying text is not legible. We suggest the largest size map for better details though the text may still be covered in the darker areas.
