The Monterey Canyon begins simply off the coast in Monterey Bay, California. It extends greater than 292 miles (470 kilometers) beneath the waves and is round 7.5 miles (12 km) throughout at its widest level. The underwater ravine has partitions as much as 5,580 toes (1,700 meters) tall, and at its deepest level the seafloor is round 2.5 miles (4 km) under the ocean’s floor.
