There are many wondrous, enigmatic and fascinating attractions on the Big Island of Hawaii, some better known than others, many out of the way and generally off the beaten track. Tour Guide Hawaii has produced an encyclopedic collection of the most up-to-date information, presented as short GPS-cued videos, in an app downloadable to iPhone and iPod Touch that covers the entire Big Island, highlighting the popular and the uncrowded, the famous and the secluded, the adventurous and the relaxing.
Mau Loa O Mauna Ulu
At Mau Loa O Mauna Ulu, flows from Mauna Ulu have crossed and re-crossed the roadway, causing it to need rebuilding a number of times. Notice the shiny glaze of the fresh lava surface, seeming impervious to the forces of nature. Yet nearby, in cracks where seeds lodge and water collects, ferns and lichens have begun to colonize these flows, some as recent as 1974.
After ferns and lichens, o’hia and other woody plants come. Here at the Park, one can see the immense role water plays in the re-vegetation of the volcanic landscape. At Mau Loa O Mauna Ulu, where it is relatively dry, re-vegetation is slow and may take half a millennium or more to cover a lava flow. Higher up, along Crater Rim Drive, you observe flows as young as a hundred years completely reclaimed by the voracious rain forest where water is abundant.
Between 1969 and 1974 Mauna Ulu erupted almost 760 billion pounds of lava, covering an area of almost 17 square miles in an average depth of 25 feet.
