What is the maximum relief of the dune field? (Compare the height of dune crests with the bottom of the depression on the lee side.)
The question is based on the “Glamis SE, California” quadrangle shown below (Figure 46-7); a stereogram of the same area is shown in Figure 46-3. The map shows a region of mostly transverse sand dunes in southeastern California (32°50'46"N, 115°00'21"W). Note that many depression contours are used on this map, but they are difficult to read because of the sand stippling. To view this map in color, go to the Lab Manual website or scan the QR code for this exercise.
