Makapu'u Coastline Oahu is the third largest island in the Hawaiian archipelago and for almost 150 years has been the political, economic and cultural center of the Hawaiian islands. Covering an area of 607sq.miles/1574sq.km, its coastline measures 137 miles/220km. Oahu evolved from two volcanoes which still exist today in the mountain ranges, Koolau Range and Waianae Range. The older of the two, Waianae Range, evolved between about 3.4 and 2.7 million years ago. Strong erosion has had such an effect that the volcanic craters can no longer be recognized clearly. Oahu is noted for its tuffs which evolved during the last phase of the volcanic creation of the island (Diamond Head, Punchbowl,Chinaman's Hat, Rabbit Island). The island is divided into four geographical areas - the Koolau Range, Waianae Range, Schofield Plateau and the flat land around the coast. Schofield Plateau is formed from lava from Koolau volcano, as is the flat coastal land. The present mountain ranges and valleys are examples of an eroded landscape. Particularly impressive is Nuuanu Pali, north of Honolulu.
