Consag Basin
The Consag Basin is a submarine depression in the far northern part of the Gulf of California associated with the East Pacific Rise. It lies south of the Wagner Basin with which it is closely linked. The depression is a result of subsidence caused by the extensional forces probably imparted by the same spreading center which has produced the Wagner Basin. Both basins are bounded on their eastern side by the Wagner Fault, a primarily normal (vertical motion) fault which dips approximately 60 degrees to the northwest. The western side of the basin is bounded by another normal fault, the Consag Fault which dips in a direction opposite the Wagner Fault. The seabed between these faults is sinking. The Consag Basin is linked to the Delfin Basin located to its south by a poorly understood deformation zone which further research may eventually define as a transform fault A transform fault or transform boundary, is a fault along a plate boundary where the motion is predominantly hor ...

Gulf Of California
The Gulf of California ( es, Golfo de California), also known as the Sea of Cortés (''Mar de Cortés'') or Sea of Cortez, or less commonly as the Vermilion Sea (''Mar Bermejo''), is a marginal sea of the Pacific Ocean that separates the Baja California Peninsula from the Mexico, Mexican mainland. It is bordered by the states of Baja California, Baja California Sur, Sonora, and Sinaloa with a coastline of approximately . Rivers that flow into the Gulf of California include the Colorado River, Colorado, Fuerte River, Fuerte, Mayo River (Mexico), Mayo, Sinaloa River, Sinaloa, Sonora River, Sonora, and the Yaqui River, Yaqui. The surface of the gulf is about . Maximum depths exceed because of the complex geology, linked to plate tectonics. The gulf is thought to be one of the most diverse seas on Earth and is home to more than 5,000 species of micro-invertebrates. Parts of the Gulf of California are a UNESCO World Heritage Site.

East Pacific Rise
The East Pacific Rise is a mid-ocean rise (termed an oceanic rise and not a mid-ocean ridge due to its higher rate of spreading that results in less elevation increase and more regular terrain), a divergent tectonic plate boundary located along the floor of the Pacific Ocean. It separates the Pacific Plate to the west from (north to south) the North American Plate, the Rivera Plate, the Cocos Plate, the Nazca Plate, and the Antarctic Plate. It runs south from the Gulf of California in the Salton Sea basin in Southern California to a point near 55° S, 130° W, where it joins the Pacific-Antarctic Ridge trending west-southwest towards Antarctica, near New Zealand (though in some uses the PAR is regarded as the southern section of the EPR). Much of the rise lies about 3200 km (2000 mi) off the South American coast and rises about 1,800–2,700 m (6,000–9,000 ft) above the surrounding seafloor.

Wagner Basin
Wagner Basin is a submarine depression in the far northern part of the Gulf of California. The basin is currently tectonically active. It is the northernmost underwater depression associated with the East Pacific Rise and is located near the southern end of the Cerro Prieto fault. The depression is a result of subsidence caused by the extensional forces imparted by a spreading center. The Wagner Basin is bounded on its eastern side by the Wagner Fault, a primarily normal (vertical motion) fault which dips approximately 60 degrees to the northwest. The western side of the basin is bounded by another normal fault, the Consag Fault which dips in a direction opposite the Wagner Fault. The seabed between these faults is sinking. The basin is linked to the dextral (right lateral-moving) Cerro Prieto Fault at its north end.

Delfin Basin
The Delfin Basin (''delfín'' is Spanish for "dolphin") is a pair of interconnected submarine depressions located on the seabed of the northern Gulf of California. The northernmost of these is called the Upper Delfin Basin while the southernmost is called the Lower Delfin Basin. Both of these features are areas of subsidence caused by extensional forces imparted by a spreading center associated with the East Pacific Rise. The two basins are linked by a short transform fault which was the apparent source of an earthquake of magnitude 5.5 on November 26, 1997. The Delfin Basin is linked to the Guaymas Basin located about 325 km to the south by a series of four transform faults called the Guaymas Transform Fault System. It is also linked to the north with the Consag Basin by way of a poorly defined deformation zone.

Transform Fault
A transform fault or transform boundary, is a fault along a plate boundary where the motion is predominantly horizontal. It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone. A transform fault is a special case of a ''strike-slip fault'' that also forms a plate boundary. Most such faults are found in oceanic crust, where they accommodate the lateral offset between segments of divergent boundaries, forming a zigzag pattern. This is a result of oblique seafloor spreading where the direction of motion is not perpendicular to the trend of the overall divergent boundary. A smaller number of such faults are found on land, although these are generally better-known, such as the San Andreas Fault and North Anatolian Fault. Nomenclature Transform boundaries are also known as conservative plate boundaries because they involve no addition or loss of lithosphere at the Earth's surface. Background Geophysicist ...

Roca Consag
Roca Consag (Consag Rock) is a granitic (or more precisely, dacitic) outcrop located in the northern Gulf of California about 22 miles ENE of the town of San Felipe. The outcrop stands about 286 feet above the sea, and is named for the Jesuit missionary Ferdinand Konščak who was active in the early exploration and missionary work in Baja California Baja California (; 'Lower California'), officially the Free and Sovereign State of Baja California ( es, Estado Libre y Soberano de Baja California), is a state in Mexico. It is the northernmost and westernmost of the 32 federal entities of Mex .... The ruins of an abandoned lighthouse can be seen on the west side of the outcrop.http://www.mexfish.com/rkyp/rkyp/af000823/af000823.htm Beyond Roca Consag: A "Different" Trip To Puerto Peñasco, mexfish.com, photo The waters in the vicinity of the Roca Consag are a popular fishing area and also favored for spotting whales and porpoises.
