This completely revised, full-color second edition of Roadside Geology of Hawai'i details the evolution of this volcanic island chain, from its first tumultuous appearance above the sea to ongoing eruptions, including the 2018 eruption of Kīlauea. Erosional landscapes dominate the older islands, such as Waimea Canyon on Kaua'i, enormous rounded rocks at Garden of the Gods on Lāna'i, and the highest shoreline cliff in the world on Molokai, the scarp of the Wailau landslide. Volcanoes, cinder cones, and craters dominate the younger islands, from Haleakalā Volcano on Maui and Diamond Head and Koko Craters on O'ahu to the active caldera in the Big Island's Hawai'i Volcanoes National Park. With this book as your guide, you'll discover waterfalls, lava tube caves, black sand beaches, and other world-famous geologic features around every bend in the road.
