The Treasure Coast is a region of the eastern shore of the U.S. state of Florida.
 It is located on the Atlantic Coast and comprises Indian River, St. Lucie, Martin, and, in some definitions, Palm Beach counties.
 The region, whose name refers to the Spanish Treasure Fleet lost in a 1715 hurricane, evidently emerged from residents' desire to distinguish themselves from Miami and the Gold Coast region to the south.
The McLarty Treasure Museum is located at 13180 North A1A on Orchid Island, north of Windsor and Vero Beach, Florida, on the barrier island at the north end of Indian River County.
 The museum occupies part of the former site of the Survivors' and Salvagers' Camp - 1715 Fleet, and is part of Sebastian Inlet State Park.
 It houses exhibits on the history of the 1715 Spanish treasure fleet,and it features artifacts, displays, and an observation deck that overlooks the Atlantic Ocean.
 An A&E Network production, "The Queen's Jewels and the 1715 Fleet", is shown, telling of the fleet's attempt to return to Spain when a hurricane struck off the Florida coast 300 years ago.
The Survivors' and Salvagers’ Camp - 1715 Fleet is a historic site on Orchid Island, Florida.
 Survivors of the destroyed 1715 Spanish Treasure Fleet established a camp at this location while awaiting rescue.
 Salvors also used the site as they recovered sunken treasure from the 1715 fleet.
 Currently, the McLarty Treasure Museum occupies part of the area.
The Battle of Cape St Vincent of 1641 took place on 4 November 1641 when a Spanish fleet commanded by Don Juan Alonso de Idiáquez y Robles intercepted a Dutch fleet led by Artus Gijsels during the Eighty Years' War.
 After a fierce battle two Dutch ships were lost but the Dutch claimed only a hundred of their men were killed; the Spanish fleet also lost 2 ships but over a thousand dead.
 The damaged Dutch fleet was forced to abandon its planned attack on the Spanish treasure fleet.
Area code 909 is a California telephone area code that covers far eastern Los Angeles County and southwestern San Bernardino County.
 The 909 area code was split from area code 714 on November 14, 1992.
 By August 1993 use of the new area code became mandatory.
 Western Riverside County was split off from 909 into area code 951 on July 17, 2004.
 Originally on that same date, the area retaining the 909 area code was to be overlaid by a new area code 752.
 However, this overlay plan was shelved prior to the 909/951 split, and area code 752 was returned to the NANPA numbering pool to be assigned at a later date.
 909 still covers small portions of Corona, Riverside, and Moreno Valley, which are in Riverside County.
Mel Fisher's Treasure Museum is located at 1322 U.S. Highway 1, Sebastian, Florida.
 It houses exhibits on archaeology and the 1715 Spanish treasure fleet.
 Taffi Fisher, Mel Fisher’s daughter, opened the museum in December 1992 in an old abandoned fire station after renovating the building.
 The museum included a working conservation laboratory used to preserve artifacts recovered from underwater with an observation window for viewing conservation work from inside the museum.
Area code 772 serves the Treasure Coast of the state of Florida.
 It covers Sebastian, Fellsmere, Vero Beach, Fort Pierce, Port St. Lucie, Jensen Beach, Stuart, Hobe Sound, Indiantown, and other areas in east central Florida.
 It was created in 2002 as a split from area code 561 when there was a need for more phone numbers (due in part to the increase of cell phone users).
The 1715 Treasure Fleet was a Spanish treasure fleet returning from the New World to Spain.
 At two in the morning on Wednesday, July 31, 1715, seven days after departing from Havana, Cuba, eleven of the twelve ships of this fleet were lost in a hurricane near present-day Vero Beach, Florida.
 Because the fleet was carrying silver, it is also known as the 1715 Plate Fleet ("plata" being the Spanish word for silver).
 Some artifacts and even coins still wash up on Florida beaches from time to time.
Urca de Lima is a Spanish shipwreck (which sank in 1715) near Fort Pierce, Florida, United States.
 She was part of the 1715 Treasure Fleet, herself, one of the numerous Spanish treasure fleets sailing between Spain and her colonies in the Americas.
 The wreck is located north of Fort Pierce Inlet, 200 yards off the shore from Jack Island Park.
 It became the first Florida Underwater Archaeological Preserve when dedicated in 1987.
 This was followed on May 31, 2001 with its addition to the U.S. National Register of Historic Places.
