Los Angeles Margin and Basin

Illustration looking at the land from out over the ocean, as if the water were drained away, to show seafloor features.

Detailed Description

Overall perspective view of the Los Angeles Margin and Basin looking northeast. The distance across the bottom of the image is about 100 kilometers with a vertical exaggeration of 6 times. The margin is bisected by a series of large underwater canyons, channels, and gullies. Underwater landslides occur along the steep slope off the Palos Verdes Peninsula (far right) depositing large blocks into the deeper basin.
