Which human-built feature nearby appears to have been influenced by the same kind of landform?

The question is based on Map T-5, a portion of the “Jackson, Mississippi-Louisiana” topographic map (scale 1:250,000; contour interval 50 feet; dashed lines are supplementary contours at 25-foot intervals). A color satellite image of this same region is shown in Figure 40-5 (scan the QR code for this exercise or go to the Lab Manual website and Exercise 40). For reference, the dashed contour line on “Paw Paw Island” in the southern part of the map shows an elevation of 75 feet. What will be an ideal response?
