In the aerial imagery (Map T-20b), notice that the dry gorge around the half-circle-shaped hill looks like a ridge surrounding a depression. Why does it appear this way?
The question is based on color Maps T-20a and T-20b (in the back of the Lab Manual) and Figure 32-3, a black-and-white stereogram, showing the entrenched meanders of the Green River near Canyonlands National Park, Utah. A larger portion of this region is shown in color Map T-7 in the back of the Lab Manual.
What will be an ideal response?
It is an optical illusion--on “shaded relief” maps the imaginary Sun shines from the northwest; in this image, the actual Sun is shining from the southeast, putting shadows on the northwest side of the hill.
