Chapter 7.1, Problem 1A

Obtain a stereoscope from your instructor, unfold it, and center it over the line that separates the two serial photographs of the volcanic core in figure 7.2. Use this stereogram to complete the following.

Figure 7.2 Stereogram of Mt. Capulin, a volcanic cinder cone located in northeastern New Mexico. The stereogram consists of two overlapping aerial photographs taken from an altitude of approximately 4800 meters (16,000 feet). To view the three-dimensional image of the volcano, center a stereoscope over the line that separates the two photographs. Then, while looking through the stereoscope, adjust the stereoscope until the image appears in three dimensions. The inset photo shows a traditional ground-level view of Mt. Capulin.

Identify and label the crater at the summit of the volcano.
