After reviewing Figures 25.1 and 25.2, answer the following questions about Figure 25.5:
Figure 25.4 shows a contour map of a hypothetical landscape that has been shaped by alpine glaciation. As glaciers carved their way down preexisting V-shaped stream valleys, they widened the valleys into U-shaped valleys separated by sharp ridges. Hanging valleys/troughs left stranded above the main valley floor will be occupied by streams that form picturesque waterfalls as they plunge over the steep edge. Glaciers may scour out the bedrock of the valley floor, leaving depressions that, as the glacier retreats and a stream reoccupies the valley, subsequently fill with water, forming glacial lakes called tarns. Steep-walled cirques mark the origin of the glaciers high on the mountain slope. Keep this contours map, along with the Mount Darwin topo map and aerial imagery, in mind when analyzing the topographic map of Mount Rainier. a) If you wanted to go swimming in a tarn, which letters would you look for? b) If you were a rock climber and wanted to scale the steep sides of the valley, which letters would you look for? c) Which letters indicate the location of a pass on the ridge between two valleys? d) If you wanted to climb the horn created by three glaciers, which letter would you look for? e) What is the elevation of the peak?
