shallow submarine canyon in the Pacific off La Jolla, Calif.; it is the best studied of all submarine canyons by virtue of its proximity to Scripps Institution of Oceanography, for which it was named. The canyon's shallow tributary valleys head very close to shore in water only 40 feet (12 m) deep. The valley joins a larger canyon, La Jolla Canyon, at an axial depth of 980 feet, 1.3 miles from its head. There the walls of Scripps Canyon are V-shaped and have a height of approximately 360 feet.
