The Pinacate Peaks lie just north of the fishing resort of Puerto Peñasco . The tallest of the peaks is Cerro del Pinacate (also called Volcan Santa Clara), with an elevation of 3,904 feet (1,190 m). The Mexican Spanish word pinacate is derived from the Nahuatl word for

For example, shallow depths are directly influenced by the local temperature of the air, while deeper waters are less susceptible to changes in air temperature. The temperature of the water in the gulf generally experiences lows of 16 °C (61 °F) in winter and highs of 24 °C (75 °F) in summer. But temperatures can vary greatly in

The salinities of these inlets are higher than that of the ocean. The temperatures, poikilothermal , of these negative estuaries also are higher than the general temperature of the gulf. It is possible that at one time these estuaries were positive, that is, ones in which

In 1826, retired Robert William Hale Hardy of the British Royal Navy was sailing in this area searching for pearls and precious metals. He named the area Rocky Point, and it was identified as Rocky Point on marine maps until President Lázaro Cárdenas changed it to Puerto Punta Peñasco. To simplify pronunciation,

This delta blocks the sea from flooding the Mexicali and Imperial Valleys . Volcanism dominates the East Pacific Rise . The island of Isla Tortuga is one example of this ongoing volcanic activity. Furthermore, hydrothermal vents due to extension tectonic regime, related to

It is now one of the most important tourist destinations in northern Mexico. Puerto Peñasco is often called " Rocky Point " in English, and has been nicknamed " Arizona’s Beach " as it is the closest beach to cities such as Phoenix and Tucson . The warm sea surface temperatures of

These are grouped into four archipelagos: San Luis Gonzaga or Enchanted, Guardian Angel, Bahía de los Ángeles and San Lorenzo. The three general types of shores found in the gulf include rocky shore , sandy beach, and tidal flat. Some of the rich biodiversity and high endemism that characterize the gulf and make it such a hotspot for fishing can be attributed to seemingly insignificant factors, such as

1404-447: The seawater component is diluted; therefore, the water is brackish , with salinity less than that of the ocean. However, because of human settlement around the gulf and water diversion for municipal and agricultural use in an area of comparatively low rainfall, there are no longer many rivers that freely empty into the gulf. The upper Colorado River Delta is one example of a historically major estuary and wetlands ecosystem, that since

In 1952, Puerto Peñasco separated from the municipality of Caborca and comprised the localities of Sonoyta, Bahía La Choya, 21 de Marzo and Cuauhtémoc. Sonoyta was the second largest population center at the time. In 1989, the municipality of Plutarco Elías Calles was split from Puerto Peñasco.
