About 79% of Iceland's land area, which is of recent volcanic origin, consists of glaciers, lakes, a mountainous lava desert (highest elevation 2,000 meters--6,590 ft.--above sea level), and other wasteland. About 28% of the land is used for grazing, and 1% is cultivated. The inhabited areas are on the coast, particularly in the southwest where about 60% of the population lives.

Because of the Gulf Stream's moderating influence, the climate is characterized by damp, cool summers and relatively mild but windy winters. In Reykjavik, the average temperature is 11ƒC (52ƒF) in July and -1ƒC (30ƒF) in January.
