... evaporites proved that the water level had been low enough for the rivers to cut the gorges subaerially. In other words, the Mediterranean's level fell several thousand feet, allowing the rivers to erode gorges much as the Colorado does today in the Grand Canyon. (Smith, E.G . Walton; "When the Mediterranean Went Dry," Sea Frontiers, 28:66, 1982.) Comment. The Med's buried gorges are obviously close cousins of the many submarine canyons found around the world's continental shelves. Most geologists strongly resist any explanation of the submarine canyons involving subaerial erosion, because no one believes the oceans ever dropped thousands of feet. True, the Med's evaporites confirm a great reduction in water level there, but the flat-topped guyots in the Atlantic and Pacific do the same for the oceans -- or at least seem to. The guyot tops are now thousands of feet below the surface, just like the Mediterranean's evaporites. It is thought-provoking to notice that the Mediterranean (and the oceans?) began to dry up about 5 million years ago, just about when humans are supposed to have split off from the other primates. Reference. Flat-topped guyots are cataloged at ETH1 in Carolina Bays, Mima Mounds. Description of this book here . From Science Frontiers #21, MAY-JUN 1982 . 1982-2000 William R. Corliss ...

... New England Seamounts have therefore either subsided on the order of a kilometer since Eocene times or sealevel has altered drastically. The Alvin dives also discovered a series of very striking and perplexing buttes obviously the results of erosion (see drawing on cover). The buttes are apparently composed of volcanic rock and are only a few meters high. Some unexplained, extremely vesicular (holefilled) rocks seen on the sea floor during the dives seem to be identical to samples occasionally dredged up and formerly classified as cinders jettisoned from old steamships. The underwater surveys suggested that these "cinders" have a natural (still mysterious) origin. (Heirtzler, J.R ., et al; "A Visit to the New England Seamounts," American Scientist, 65:466, 1977.)
