Hawaii - James Michener [6]
In time, sinking lava from the second master builder began to creep across the feet of the first, and then to climb its sides and finally to throw itself across the exposed lava flows that had constituted the earlier island. Now the void in the sea that had separated the two was filled, and they became one. Locked in fiery aims, joined by intertwining ejaculations of molten rock, the two volcanoes stood in matrimony, their union a single fruitful and growing island. Its soil was later made from dozens of smaller volcanoes that erupted for a few hundred thousand years, then passed into death and silence. One exploded in dazzling glory and left a crater looking like a punch bowl. Another, at the very edge of the island, from where it could control the sea approaches, left as its memory a gaunt headland shaped like a diamond.
When the island was well formed--and what a heavenly, sweet, enchanting island it was--some force of nature, almost as if by subtle plan, hid in its bowels a wealth of incalculable richness. It could not be diamonds, because the island was 250,000,000 years too young to have acquired the carboniferous plant growth that produced diamonds. It could not be either oil or coal, for the same reason. It wasn't gold, for neither the age nor the conditions required for the building of that metal were present on this island. It was none of these commonly accepted treasures, but it was a greater.
The volcanic basalt from which the island was built was porous, and when the tremendous storms which swept the ocean struck the island, the waters they disgorged ran partly out to sea in surface rivers, seeped partly into the heart of the island. Billions of tons of water thus crept down into the secret reservoirs of the island.
They did not stay there, of course, for since the rock was porous, there were avenues that led back out to sea, and in time the water was lost. But if any animal--a man perhaps--could penetrate the rocks, he could intercept the water and put it to his use, for the entire island was a catchment; the entire core of the island was permeated with life-giving water.
But that was not the special treasure of this particular island, for a man could bore into almost any porous rock on any island, and catch some water. Here, on this island, there was to be an extra treasure, and the way it was deposited was something of a miracle.
When the ice came and went, causing the great ocean to rise, when the island itself sank slowly and then rebuilt with new lava-- when these titanic convolutions were in progress, the south shore of the island was alternately exposed to sunlight or buried fathoms deep in ocean. When the first condition prevailed, the exposed shore was cut by mountain streams which threw their debris across the plain, depositing there claylike soils and minute fragments of lava. Sometimes the sea would wash in bits of animal calcium, or a thundering storm would rip away a cliff face and throw its remnants over the shore. Bit by bit, over a hundred thousand years at a time, the shore accumulated its debris.
Then, when next the ocean rose, it would press down heavily upon this shelving land, which would lie for ages, submerged under tons of dark, green water. But while the great brutal ocean thus pressed down hydraulically, it at the same time acted as a life-giving agent, for through its shimmering waves filtered silt and dead bodies and water-logged fragments of trees and sand. All these things, the gifts both of land and sea, the immense weight of ocean would bind together until they united to form rock.
Cataclysmically the island would rise from the sea to collect new fragments washed down from the hills, then sink beneath the waves to accumulate new deposits of life-building slime. But whenever the monstrous ocean would beat down heavily upon the shore for ten thousand years at a time, new rock was formed, an impermeable shield that sloped down from the lower foothills and extended well out to sea. It was a cap rock,
