Kahoolawe is the smallest of the 8 main volcanic islands in the Hawaiian Islands. It is located 7 miles (11.2 km) southwest of Maui and southeast of Lānai and is 18 km (11 miles) long by 10 km (6 miles) across. Total area is 115.5 km² (44.6 mile²). The highest point is the crater of Lua Makika at the summit of Puu Moaulanui, which is 450 m (1,477 ft) above sea level. The island is relatively dry because the low elevation fails to generate much orographic precipitation from the northeastern trade winds and it is located in the rain shadow of Maui's 3055 m (10,023 ft) high East Maui Volcano (Haleakalā). More than one quarter of the island has been eroded down to saprolitichardpan.
