The mountain terminates in a crater nearly 32 km (nearly 20 mi) in circumference and more than 924 m (more than 3028 ft) deep. West Maui rises to an elevation of 1764 m (5788 ft) and has many sharp peaks and ridges and extensive sloping plains on the northern and southern sides. Pineapple and large sugar plantations and cattle ranches are here. Tourism, construction, and scientific research are also important to the economy. Wailuku is the chief community.
