Kahoʻolawe (/kəˌhoʊ.əˈlɑːwiː/; Hawaiian: [kəˈhoʔoˈlɐve]) is the smallest of the eight main volcanic islands in the Hawaiian Islands. Kahoʻolawe is located about seven miles (11.2 km) southwest of Maui and also southeast of Lanai, and it is 11 miles (18 km) long by 6.0 miles (9.7 km) wide, with a total land area of 44.97 square miles (116.5 km²). The highest point on Kahoʻolawe is the crater of Lua Makika at the summit of Puʻu Moaulanui, which is about 1,477 feet (450 m) above sea level. Kahoʻolawe is relatively dry (average annual rainfall is less than 65 cm or 26 in) because the island's low elevation fails to generate much orographic precipitation from the northeastern trade winds, and Kahoolawe is located in the rain shadow of eastern Maui's 10,023 feet (3,055 m) high volcano, Haleakalā.
