Turks and Caicos Island Chain#Caicos Islands, Turks- und Caicosinseln are relatively large, compared to the few dozen smaller islands in this archipelago. Only five of the larger islands and a few of the smaller ones support human populations, and all of these low-lying islands sit atop undersea pillars of coral.
This is a satellite image of the easternmost part of the island chain. Shown here are Grand Turk, its southerly neighbor Salt Cay, and several smaller islands. The coral surrounding the landmasses glows peacock blue; the areas above water show a combination of vegetation and cityscape.
