Guide to Magellan Image Interpretation

Figure 4-8. Caldera (volcanic pit): (a) Cycle 1 image with illumination from the left at an incidence angle of 42.5 deg.; (b) Cycle 3 image with illumination from the left at an incidence angle of 22.7 deg. The center coordinates are 9.5°S, 69°E. The parallax difference between features on the rim and floor gives a depth of 1.3 km for the caldera.
