Science Frontiers ONLINE No. 50: Mar-Apr 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Whales And Seafloor Pits Typical sizes, shapes, and disposition of whale-excavated pits in the Bering Sea. The focus of a 1987 paper in Scientific American, by C.H . Nelson and K.R . Johnson, is the northeastern Bering Sea, where sensitive side-scanning sonar has sketched large numbers of pits and furrows in the shallow sands. The pits range from 1-10 meters in length, 0.5 -7 meters in width, and 0.1 -0 .4 meters in depth. No known geological processes seem responsible. Farther east, in Nor-ton Sound, methane eruptions from buried ... matter do blow out circular craters; but the elongated pits investigated by Nelson and Johnson are gouged in sand considered too permeable for gas-crater formation. Rather surprisingly, the gray whale has become suspect as a pit excavator. They feed in the area of the pits; and the pits, before enlargement by currents, are just the size of the whales' mouths. The whales apparently dredge up sediment and, with their baleen, strain out amphipods (shrimp-like crustaceans) from the sand. The coexisting narrow furrows turn out to be the work of walruses digging for clams. (Nelson, C. Hans, and Johnson, Kirk R.; "Whales and Walruses as Tillers of the Sea Floor," Scientific American, 256:112, February 1987.) Comment ...

... Parts of these roads were actually carved into the island's bedrock-lava flows mainly. Strangely, the roads were not flat but V- and U-shaped in cross section. They averaged 3.5 meters (11.5 feet) wide and were not a trivial undertaking. In some sections, the roads were flanked by lines of rocks. Sometimes these curbstones were accompanied by pits gouged out of the solid rock. Usually, the pits occurred where the roads sloped uphill. Love speculates that the pits were dug to accommodate some "mechanism" invented to help move the multi-ton heads up the inclines -- a primitive cog railway of sorts. The pits and V-shaped profiles suggest that we still have much to learn about the Easter Island roads and exactly ... the ahu. Thor Heyerdahl and others have even managed to duplicate some phases of the operation. However, the voluminous Easter Island literature is not as forthcoming about the roads the natives built to accelerate this Ethic traffic. The Easter Island roads have turned out to be as curious as the statues themselves. During the summer of 2000, geologist C.M . Love and a crew of 17 students excavated sections of the three main roads that carried statue traffic. Parts of these roads were actually carved into the island's bedrock-lava flows mainly. Strangely, the roads were not flat but V- and U-shaped in cross section. They averaged 3.5 meters (11.5 feet) wide and were not a trivial undertaking. In some sections, the roads were ...

The diggers found bones, worked flints, and burnt stones arranged in a ring. Excavations were stopped when the importance of the site became obvious. Estimates of the campsite's age were as old as 30,000 years -- a figure that would have been heresy a decade or two ago. (Anonymous; "Ancient Camp Unearthed at Colo.

... ). Obviously, we are not dealing with minor earth-moving operations here. (Anonymous; "The Gruyerization of Switzerland," The Cerealogist , no. 3, p. 26, Spring 1991. The Cerealogist is a British publication focussing on the crop-circle phenomenon.) Comment. Could the "force" flattening the crop circles also gouge out cookiecutter holes and the Swiss cavernous pits? Additional information on the Swiss excavations and similar events is certainly required. Anomalists know from experience that for every strange phenomenon there exists a hoaxer anxious to reproduce it. Reference.

Science Frontiers ONLINE No. 77: Sep-Oct 1991 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Gruyerizaton Of Switzerland An impressive and equally inexplicable variety of the cookie-cutter holes has been reported in Switzerland. In these excavation phenomena, all the material removed from the holes has disappeared instead of being translated intact and set down gently nearby. "The Swiss holes were first observed in 1972. They always occur at night and no one has ever seen them forming. They are circular, drilled deep into the earth, and are created by the total removal of vegetation and soil. A large fleet of lorries would be needed to move the quantities of earth involved, but there are no vehicle marks around the holes. The grass ...

... of earlier configurations, hints of trials and errors, and just plain enigmas. The hidden or cryptic Stonehenge is found mostly by accident when some chance digging reveals a previously unrecorded hole, ditch, or buried artifact. To illustrate, in May and June of 1979, a 24-meter trench was excavated along the path of a proposed telephone cable. The diggers found a completely unexpected, backfilled pit showing the impression of the standing stone that had once occupied it. Now called Stone 97, this feature was "erased" thousands of years ago for some unknown reason. Several such fortuitous finds hint that the Stonehenge we now see is like one of those paintings painted over an earlier painting.

... 12,500 years old. Reason #2 is the distance gap of about 5,000 miles between the two sites. So far, there is no evidence of cultural continuity. The time gap is likely to enlarge in a huge quantum jump because of excavations at an intriguing green knoll at Monte Verde. Some 6 feet below its surface is a sedimentary layer containing charcoal in clay-lined pits and humanfractured pebbles. This sedimentary layer is carbon-dated at 33,000 years ago -- some 20,000 years before the ancestors of North America's Clovis people are said to have trekked across the Bering land bridge.
