Figure 5--North-south stratigraphic well-log cross section (A-A') of subsurface Missourian formations across western Kansas (see figure 4 for location). Shelf-basin transition illustrated for Lansing Group. Section datum is top of Lansing Group. Correlation lines from upper to lower are top of Lansing Group, top of Kansas City Group, and base of Kansas City Group. Subsea elevations of the top of Lansing and base of Kansas City groups are included in the figure.

Lansing thickens to south; Kansas City seems to average the same thickness from north to south. Depth increases to south.
