... . Imagine what happened as this water flowed across North America. Many geologists look askance at Shaw's theory of drumlin formation. (Monastersky, R.; "Hills Point to Catastrophic Ice Age Floods," Science News, 136:213, 1989.) Comment. The famous Channelled Scablands in the Pacific Northwest are thought to have been scoured out when an ice dam broke unleashing the Spokane Flood near the end of the Ice Ages. These land forms are described in our catalog: Carolina Bays, Mima Mounds. For details on this volume visit: here . From Science Frontiers #66, NOV-DEC 1989 . 1989-2000 William R. Corliss ...

... feet deep, containing 200 cubic miles of water. When the ice dam suddenly ruptured, all life and land downstream was devastated. (Folger, Tim; "The Biggest Flood," Discover, 15:36, January 1994.) Comment. The breaking of Pleistocene ice dams also carved up parts of North America. There was the famous Cincinnati ice dam and, of course, the Spokane Flood that gouged out the Channelled Scablands of the Pacific Northwest, when Lake Missoula catastrophically emptied into the Pacific. See ETM5 in our catalog: Carolina Bays, Mima Mounds. It is described here . But other thoughts intrude: Were the heaps of mammoth carcasses, the Siberian "ivory islands," and those anomalous stone tools mentioned earlier under Archeology the consequences similar Siberian floods?

Deep in the Altai Mountains of southern Siberia. About this date, a wall of water 1,500 feet high surged down the Chuja River valley at 90 miles per hour. How does one deduce such a hydrological cataclysm? A. Rudoy, a geologist at Tomsky State Pedagogical Institute, points to giant gravel bars along the Chuja River valley. These are not the inch-sized ripples we seen on the floors of today's rivers; these are giants measuring tens of yards from crest to crest. Only a catastrophic flood could have piled up these ridges of ...

Science Frontiers ONLINE No. 16: Summer 1981 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects A MARTIAN ICE AGE?Long, sinuous depressions called "outflow channels" are concentrated in the equatorial regions of Mars. They clearly resemble terrestrial stream beds and have been attributed to water action. The ancient Spokane Flood that carved our Washington State's channeled scablands is seen as an apt terrestrial analogy. The Martian channels, however, are much larger than the water-eroded terrestrial analogs. The authors of the subject paper suggest that ice rather than water created the Martian channels, pointing out that terrestrial ice-stream and glacier landforms are much closer to the Martian features in terms of scale. (Lucchitta, Baerbel K., et al ... "Did Ice Streams Carve Martian Outflow Channels?" Nature, 290:759, 1981.) Comment. This suggests the possibility that earth and Mars may have had synchronous Ice Ages due to solar variations or, perhaps, the envelopment of the entire solar system by a huge cloud of absorbing matter.
