Guide to Important Geological Locations.  The host for this episode is Mitch Ewan.  The guest for this episode is Michael Knight.

A tour through the geological story of O’ahu by exploring 39 areas of natural beauty, many off the beaten path, and connecting all geology enthusiasts (young scientists) with the ‘ānia (earth or land), nature, and some of cultural history of our island. 

The geology of O’ahu and how it relates to Hawaiian hotspot volcanism, i.e., compare O’ahu’s eroded volcanoes to the recent active eruptions at Kïlauea Volcano on the Big Island (illustrating a simple magma chamber and rift zone of the eruptions).

Discuss how to use this guidebook to visit some of the interesting landform areas on O’ahu, either by car, bus, bicycle, canoe, surfboard, or walking to 39 of the most important and easily reachable geologic sites, if you have the time and interest.

How O’ahu formed from three large shield volcanos each shouldering on the next.

How magma moved through these volcanoes through the rift systems and dike complex. 


Hawaiian mythologies related to the Hawaiian Goddess Pele.
