Question: San Lucas Canyon is a submarine canyon off coast of which city?

Context paragraphs:
Zhemchug Canyon: Zhemchug Canyon is an underwater canyon located in the middle of the Bering Sea.  This submarine canyon is the deepest and is tied for widest canyon in the ocean.

Hudson Canyon: The Hudson Canyon is a submarine canyon that begins from the shallow outlet of the estuary at the mouth of the Hudson River.  It extends out over 400 mi seaward across the continental shelf finally connecting to the deep ocean basin at a depth of 3 to 4 km below sea level.  It begins as a natural channel of several kilometers width, starting as a 20-40 m depression at Hudson Channel southward from Ambrose Light, then carving through a deep notch of about 1 km depth in the shelf break, and running down the continental rise.  Tidally associated flows of about 30 cm/s (1 km/h) up and down the deeper parts of the canyon have been recorded.  As silt, sand and mud are carried down the Hudson River, they flow into the canyon and out into the deep sea.

Delgada Submarine Canyon: The Delgada Submarine Canyon is an underwater submarine canyon located off the King Range in Northern California.  A million cubic meters of sediment fall into this canyon and another canyon each year.  One end is near the coastline, close to Shelter Cove, part of the Lost Coast of California.  The Delgada deep-sea fan is located at the mouth of the canyon.

Monterey Canyon: Monterey Canyon, or Monterey Submarine Canyon, is a submarine canyon in Monterey Bay, California with steep canyon walls measuring a full 1 mile in height from bottom to top, which height/ depth rivals the depth of the Grand Canyon itself.  It is the largest such submarine canyon along the West coast of the North American continent, and was formed by the underwater erosion process known as turbidity current erosion.  Many questions remain as yet unresolved regarding the exact nature of its origins, and as such it is the subject of several ongoing geological and marine life studies being carried out by scientists stationed at the nearby Monterey Bay Aquarium Research Institute, the Moss Landing Marine Laboratories, and other oceanographic institutions.

Mississippi Canyon: The Mississippi Canyon is an undersea canyon, part of the Mississippi Submarine Valley in the North-central Gulf of Mexico, south of Louisiana.  According to the U.S. Geological Survey GLORIA Mapping Program, it is the dominant feature of the north-central Gulf of Mexico.  According to GCAGS Transactions, it has an average width of 8 km , and a length of 120 km .  The US Minerals Management Service (MMS) applies the name Mississippi Canyon to numbered federal oil and gas lease blocks over a large offshore area centered on, but mostly outside, the submarine canyon.

Great Bahama Canyon: The Great Bahama Canyon is a V-shaped submarine canyon system in the Bahamas that cuts between the Abaco Islands to the north and Eleuthera island to the south.  It separates the Bahama Banks and forms one of the deepest underwater canyon systems known.  There are three branches: the Tongue of the Ocean running south between the Andros and New Providence, and the northeast and northwest Providence Channel.  The canyon walls reach heights of 5 km ; taller than any canyon walls on land.  This canyon system has remained open through a process of submarine erosion.

Cabo San Lucas: Cabo San Lucas (] , "Cape Saint Luke"), commonly called Cabo in American English, is a city at the southern tip of the Baja California Peninsula, in the Mexican state of Baja California Sur.  Cabo San Lucas together with San José del Cabo is known as Los Cabos.

Navarin Canyon: The Navarin Canyon is a submarine canyon in the Bering Sea.  It is just as wide but less than half as deep as the Zhemchug Canyon, which is the largest canyon in the world.

San Lucas Canyon: San Lucas Canyon is a submarine canyon off Cabo San Lucas, Baja California Sur.  The canyon is home to some spectacular submarine phenomena, namely the "rivers of sand" and sandfalls.  These were first observed in 1959 by an expedition led by D. F. Shepard and including Conrad Limbaugh, James Steward, and Wheeler J. North.  These features were documented by Robert F. Dill (1964) and dived, filmed and made famous by Jacques Cousteau.

Submarine canyon: A submarine canyon is a steep-sided valley cut into the seabed of the continental slope, sometimes extending well onto the continental shelf, having nearly vertical walls, and occasionally having canyon wall heights of up to 5 km, from canyon floor to canyon rim, as with the Great Bahama Canyon.  Just as above-sea-level canyons serve as channels for the flow of water across land, submarine canyons serve as channels for the flow of turbidity currents across the seafloor.  Turbidity currents are flows of dense, sediment laden waters that are supplied by rivers, or generated on the seabed by storms, submarine landslides, earthquakes, and other soil disturbances.  Turbidity currents travel down slope at great speed (as much as 70 km/h), eroding the continental slope and finally depositing sediment onto the abyssal plain, where the particles settle out.
