Excerpt from Hawaii: Past and Present Geologically the Islands are composed of two kinds of lava rock, one completely fused and very hard, the other only partly fused (tufa), which was thrown out by the ancient volcanoes in masses and in smaller particles. Tufa decomposes under the action of erosion much more quickly than does the solid lava, but this, after centuries of wear and tear by the weather and of being broken by the roots of plants that somehow find means of life even on very recent lava flows, makes a far richer soil. Where there is not too much rain it becomes a deep red earth, the best on the Islands for agri cultural purposes except the sedimentary soil in the valley bottoms and along the coast. The only non-volcanic rock, a certain amount of sandstone and of coral, is the result of the Uplifting of ancient reefs.
