The Pinnacles (Gulf of Mexico) The Pinnacles (Gulf of Mexico) The Pinnacles is a rocky prominence on the Continental Shelf approximately 300 feet deep and located about 70 miles off the coasts of Mississippi and Alabama which contains a wide-ranging reef formation. The Pinnacles reefs consist of a lush fauna of hard, soft and, black corals, fixed sea lilies and sponges. The reef creates a living habitat for a well-developed and diverse fish culture. Snappers and groupers spawn here. Typical Caribbean reef fishes and Carolinian shelf fishes, along with epipelagic fishes, and a few deep-sea fishes populate the reef. The Pinnacles reefs are currently too
Gulf of Mexico basin shallow-marine siliciclastics; eventually sediments grade into the Cretaceous carbonates, evaporites, and chalks. More recently, the Laramide Orogeny and consequential uplift of the Rocky Mountains, which led to increased sediments flooding the gulf, is responsible for the rapid loading and burial of the Wilcox Formation (pg 43), which is one of the deepwater Gulf of Mexico formations currently being exploited for hydrocarbons. This rapid loading is also responsible for the first salt flows from beneath the basin-margin region towards the continental slope.
