...Last week in Hawaii eyewitnesses guessed the tsunami ran as high as 100 feet. Best estimate: 45 feet. Either way, they were enough to smash the city of Hilo on the exposed northeast side of the island of Hawaii, kill some 200 of its inhabitants, deposit 14 feet of silt in its harbor and wriggling fish in its coconut palms...
...explosion proved entirely harmless. This coincidence suggested, thought Dr. Evans, that radioactive residues, carried into the upper atmosphere in New Mexico, had fallen with the rain on Illinois. The only other apparent possibility was that the Wabash River, whose water was used in the strawboard factory, carried radioactive silt...
Among the chief things oceanographers would like to know is the nature of 1) the mud and silt deposits, believed to range from 600 feet to seven and a half miles thick, which cover the ocean bottom, and 2) the earth's suboceanic ribs under these deposits. Ewing has already discovered sand ripples in ocean bottoms as deep as 600 feet, indicating previously unsuspected currents. To pursue a theory that cold water moves along the ocean bottom from the poles to the equator, Ewing plans to photograph the movement of dye released on the ocean floor...
...Helmericks soon found that the surly Yukon was no highway of ro mance. It carried "the silt of half a continent," and floating forests of trees and driftwood were a daily threat to the frail Queen Beaver. Arctic breezes whipped up icy waves that drenched the honeymooners to their skins. When they spent the night on a river island their down-lined sleeping bags were soon sodden with stagnant water...
...surprising number of things, from man's moods to the size of the elephant population, show up-& -down patterns that are almost as regular as the rise & fall of the tide. Some are verified by observations covering many centuries (e.g., by means of tree rings and silt deposits in lakes, rainfall cycles have been traced back thousands of years). Other cycle records as yet are little more than preliminary observations. But despite distortions by war and catastrophe, they run remarkably true to form. Samples...
