Isopachs


     This map contains isopachs, which are lines connecting points beneath which a particular stratum or group of strata has the same thickness. This example shows the isopach of flood deposits along the Brazos River in Texas. It shows the thickness of sediment deposits from flood and uses colors to distinguish more easily between the different levels. The thickness of the deposits is measured in centimeters.
