Supplemental Information


 >border: A polygon that encompasses the maximum geographic extent of the data observations
 >SubCropDepthContours: Lines that record depth to the top Mesozoic (base Tertiary) unconformity surface in the Cook Inlet Basin. Depth is measured to top of Mesozoic unconformity in feet below sea level. Contour interval is 1000 ft. The structural surface onto which the subcrop map is projected is taken directly from the top Mesozoic unconformity depth map published by Shellenbaum and others (2010).
 >SubCropFaults: Lines that record faults that bound map units and dangling faults, modified NCGMP09 format.
 >SubCropMapUnitContacts: Lines that record map unit contacts and degree of certainty, modified NCGMP09 format.
 >SubCropMapUnitPolys: Polygons that record the distribution of interpreted geologic units, modified NCGMP09 format.
