Cross sections are constructed based upon the interpretations of
the authors made from geologic mapping, and available subsurface
(drillhole) data. Cross sections should be used as an aid to
understanding the general geologic framework of the map area,
and not be the sole source of information for use in locating or
designing wells, buildings, roads, or other man-made structures.
