    Abstract

    Until recently, much of our contemporary understanding of basalt lava tubes came from the exploration and study of caves on the U.S. mainland. Lava caves were thought of as short, segmented, “subway tubes” with little secondary formation. In the late 1980’s, cavers started to explore and map the lava tubes of Hawai‘i. They found cave systems that ran for many kilometers, had multiple levels and complex braiding, and were so deep that they set several depth records within the U.S. The cavers also discovered that the tubes had multiple stages of secondary formation growth, and had many minerals that were only expected in limestone caves. The tubes also contained bone deposits of extinct species, several archeological sites, and many cave dwelling organisms. This talk will be a tour of some of the major cave systems of Hawai‘i, and about some of the unusual features found by the cavers.

    Cindy Heazlit

    Cindy Heazlit is a member of the Hawai‘i Speleological Survey, a fellow of the Cave Research Foundation, a fellow of the National Speleological Society, and on the Board of Directors for the Cave Conservancy of Hawai‘i. She has participated and led cave science expeditions within Lava Beds National Monument, and Sequoia and Kings Canyon National Parks. She has helped map California’s longest and deepest caves, and has participated in several cave surveys in Hawai‘i. She is currently working with other members of the Hawai‘i Speleological Survey on mapping Emisine Cave, the 6th deepest cave in the U.S., and Kipuka Kanohina, which is the 2nd longest lava tube known in the world. She recently became a co-owner of a cave in Hawaii, and is now learning the joys and frustrations of cave resource management.
