When viewed without a stereoscope, the shadow on the left side (the north side) of this hill appears larger in the left image than in the right image. Why?
The question is based on Figure 32-3, a black-and-white stereogram, and color Maps T-20a and T-20b (in the back of the Lab Manual). These maps show 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.
Begin by looking at the flat-topped, half-circle-shaped hill about 4 centimeters (1.5 inches) from the bottom of the stereogram.
What will be an ideal response?
Photographs were taken from different locations--right photograph was taken from almost directly over the hill.
