West Maui Mountains

The West Maui Mountains or West Maui Volcano, known to the Hawaiians as Maui Komohana and to geologists as Mauna Kahalawai, forms a much eroded shield volcano that constitutes the western one-quarter of the Hawaiian Island of Maui. Since its last eruption approximately 320,000 years ago, the West Maui Mountains have undergone substantial stream erosion.
