The four main islands,from lower right to upper left,are: Big Island (Hawaii Island),Maui,Oahu,and Kauai. The three smaller islands to the left of Maui are (top to bottom): Molokai,Lanai,and Kahoolawe. The highest point is the peak of the Mauna Kea volcano (on Big Island),at 4205 metres elevation |
