It is possibly named after the peculiarly spherical pebbles found at its western tip. The island, the fifth largest in the Falklands archipelago, stretches for 35 kilometres and about 6 kilometres at its widest point, with a total area of 103.36 km². Its three high points are First Mountain 277 m, Middle Mountain 214 m and Marble Mountain 237 m, all of which lie in the western part of the island. The eastern part of the island has lakes and wetlands and is of high conservation value. The two halves are joined by an isthmus on which lies Pebble Island Settlement where the inhabitants live. The island has been a sheep farm since 1846; 6,000 Corriedale sheep are farmed, along with 125 head of beef and dairy cattle.
