Figure 9.9 is a stereogram showing a portion of the area covered by the Whitewater, Wisconsin, topographic map (Figure 9.10, page 160). Use the stereogram and the map to complete the following. 7. The streamlined, asymmetrical hills composed of till, labeled B, are what type of feature? 8. Examine the shape of the features labeled B on the map in Figure 9.10. How can these features be used to determine the direction of ice flow in a glaciated area? 9. Using the features labeled B in Figure 9.10 as a guide, draw an arrow on the map to indicate the direction of ice movement that occurred in this region. 10. What is the likely location of the outwash plain on the map? Identify and label the area "outwash plain." (Hint: Refer to Figure 9.7.) 11. Label the area covered by ground moraine. 12.
