The numbers on Figure 2-M6 represent the depths below sea level of an unconformity separating crystalline metamorphic basement from Mesozoic cover strata in Bloomer County.The cover strata are horizontal. (20

pts) Construct an interpretive (freehand) structure-contour map of the basement/coverа.unconformity. Use a contour interval of 20 meters. CIs.b. At what depth does well C1 penetrate the basement? (Hint: use interpolation) c. Describe what you see on this structure-contour map.
