Isopach Maps

http://www.geoexpro.com/article/The_Only_Complete_Regional_Perspective/c3301c49.aspx
This is a Isopach map which shows the thickness of rock or land using contour lines. These are commonly used for resource excavation purposes such as coal, graphite, gold, etc. This specific map shows the thickness of the lower region of Texas into the Panhandle region. You can see the isopach lines as they nearer the east coast become thinner.
