Caption from Recognition on Space Photographs of Structural Elements of Baja California – Figure 6 – Photograph looking steeply downward at the Salton depression, southern California and northern Baja California. The alined canyons of the Sierra Cucapas (lower center) mark strike-slip faults. The high normal-fault scarp of the Sierra Juarez is obvious at lower left. The San Andreas fault trends northwestward (toward upper left, across upper third of picture) but is not apparent on the photograph. The ranges northeast (above and right) of the San Andreas may be outlined primarily by strike-slip faults, but these cannot be identified in the picture.
