Summer 2013: Big Island's Kilauea Volcano spews molten lava into the sea
Nearby on the island of Maui is Mt. Haleakala, which boasts incredible altitude and an other-worldly caldera (now dormant). You can see more of Mt. Haleakala here, beginning with its high-altitude nature, such as theseMaui cows. There are many adaptations at the crater's edge, including one of the most amazing (and rarest) plants on earth, the Haleakala Silversword.
