A strong consensus has these small, drop like glassy bodies originating when meteors smash into the earth, liquifying themselves and some of the surface rocks. The resulting liquid droplets solidify in flight and when they descend form "strewn fields" hundreds, even thousands, of miles in extent. The main argument has been over whether the actual impact craters giving rise to the tektites might actually be on the moon instead of the earth. Looking over the literature, one sees that this debate has been characterized by much invective and scientific infighting. Today, most scientists concur that some tektite strewn fields are definitely associated with specific, although distant, meteor craters on the earth's surface. Unfortunately, the large separations of craters and strewn fields add a circumstantial flavor to the evidence. However, some tektite-like objects are to be found in the immediate vicinities of terrestrial craters, but not in far-flung strewn fields; viz., the Aouelloul Crater in Mauritania, and the Zhamashin Crater in the USSR. Another example has now come to light: the Lonar Lake Crater, a 50,000-year-old impact crater, in the Deccan flood basalts in India.

February 7, 1988. Near Lancaster, England It was a day with modest winds of 5-10 mph, with some gusts to 20 mph. Suddenly at 2100 GMT, the anemometer at Hazelrigg weather station registered a gust at 106 mph. Almost immediately after, the wind dropped to only 5 mph. A gust of this strength should have caused considerable damage. A few branches and twigs were down in a nearby wood, but the major effect seems to have been the transportation of a 75-kilogram sheep feeding trough across a distance of 5.1 meters! Conclusion: A sudden, small squall had passed through. (Reynolds, David J.; "Unusual Gust of Wind in Lancashire 7th February 1988," Journal of Meteorology U.K . , 13:284, 1988.) Comment.

The meteorologists attribute these circles to unseen vortices in the atmos phere; more radical speculators invoke UFOs and mysterious Russian weapons. Pertinent to the explanation of this phenomenon are recent sightings of vapor vortices in regions where crop circles are common. While no one has yet seen these vortices gouging out circles, these visual manifestations betoken strong circular winds in the proper locations. Here follows a recent account: "Looking across the field of winter wheat to the east..., he suddenly noticed at a distance of 80 metres... what he took to be a large puff of white 'bonfire smoke' rising to 15 feet (5m) maximum height. The outer part of this 'smoke' column was scarcely rotating but the middle part, which was too thick to see through, was spinning rapidly. In a couple of seconds the effect had ended; the spinning central column had gone and the residual 'smoke' or cloud of fog drifted gently in the prevailing light north-east wind towards the southwest and dissolved after going several yards. He used the word smoke out of convenience but said that the effect was more likely caused by water vapour, cloud droplets or fog. He further emphasized the swiftness of the appearance and disappearance of the phenomenon. It had arrived suddenly ...

Crew suggests in this paper that two rare classes of meteorological observations may be created by the intense electrostatic accelerating forces present in lightning channels. The first class of observations consists of blasts of hot air noted some distance from violent lightning strikes but seeming associated with the discharges. Second, some superhailstones (hydrometeors) also seem to be correlated with violent lightning. The physical mechanism for the concentration and propulsion of matter is the electrostatic force naturally present in lightning discharge channels; it functions much the same as the particle accelerators in the physics lab. The observations of hot air blasts and superhailstones collected by Crew to support his theory are indeed suggestive, but more are needed. Crew also feels that some UFO sightings may be produced by the same mechanism. (Crew, E.W .; "Meteorological Flying Objects," Royal Astronomical Society Quarterly Journal, 21:216, 1980.) Comment. Note also that the fall of thunderstones is usually coincident with lightning discharges; and that some high quality observations of thunderstone falls are on record -- despite the tendency of Science to relegate them to myth. One must also consider the possibility that the passage of a meteor or superhailstone through the atmosphere might trigger lightning, thus putting the cart before the horse.

During the 10-minute flight, more than 500 lightning-related events were recorded over that part of the globe visible from the rocket's altitude. "Among these is a class of about 23 events all having an anomalous signature, with obvious clustering of optical impulses or continuous emissions, and resulting durations of several hundred milliseconds. Such durations are much longer than typical for lightning-related events recorded at the rocket, which are more frequent overall. Every anomalous optical event (AOE) was accompanied by broadband VLF signals of a distinctive character...In considering possible sources above 30 km we find that the AOEs do not seem to resemble other natural optical phenomena, such as meteors which burn up well above 30 km in the mid-latitude atmosphere."

The Pacific Coast was moving north while the rest of North America was heading south! Then, in 1978, the strain eased in the far south of California only to reassert itself in a few weeks. This strange relaxation of strain seemed to propagate slowly across southern California, as seen by other instruments farther north. As the wave of relaxation moved ponderously along, like a slow flexure of the earth's strata, microearthquakes almost disappeared while the flow of radon from the ground increased, as one might expect. When the strain reappeared, radon flow diminished and a rash of microearthquakes were detected. It took about a year for the strain wave, called a "seismic ghost" by the geophysicists, to flow north from the Imperial Valley into the Los Angeles area.

They are found primarily in four strew fields in Europe, Australia, North America, and Africa. Just about everyone believes that tektites are once-liquid droplets of rock that were solidified in flight. The major question -- often intemperately debated -- is the location of the tektite source. Are they of terrestrial, lunar, cometary, or some other origin? A recent study by Shaw and Wasserberg, using element abundances as a guide, strongly favors a terrestrial origin, with meteor impacts serving as the liquefying and splashing agents. Indeed, specific craters have long been associated with the European and African strew fields. Those who believe that the tektites were splashed all the way from the moon by meteor impacts have not given up yet. One provocative fact stressed in this article is that the ages of the four groups of tektites are 35, 14, 1.3 , and 0.7 million years. Tektites are all quite young! (Smith, Peter J.; "The Origin of Tektites -- Settled at Last?" Nature, 300: 217, 1982.) Comment. Were there no tektite-forming meteor impacts prior to 35 millions of years ago?

Hansen sent the accompanying mosaic of Landsat photographs of northwestern Nebraska. On this, the famous Nebraska sandhills appear like giant ripples. The width of the mosaic is about 340 kilometers, so you can appreciate the scale of the hills themselves. The crest-to-crest distances seem to be 2-3 kilometers. Roughly 35,000 square kilometers are covered with a sheet of sand that averages 8 meters thick. Mainstream geologists write these sandhills off as eolian (wind-carried) deposits laid down during the late Pleistocene. Hansen, however, along with geological iconoclast A. Kelly, demur. The Nebraska sanhills, they aver, were actually deposited by a wall of water sweeping down across the continent from the north -- very likely the consequence of an impact of a large asteroid.

A preliminary analysis by Michael Mumma, of Goddard Space Flight Center in Maryland, and his colleagues. indicated that processes analogous to optical pumping in laboratory lasers were taking place and led to the coining of the term 'natural lasers.' Now, Deming and colleagues from the Goddard team have taken new observations of emission from Mars and Venus at wavelengths near 10 micrometers. and modelled them to show that stimulated emission -- the effect which makes lasers so powerful -- accounts for up to seven per cent of the total emission. This is not a large amplification factor by laboratory standards, particularly for a CO2 laser. But, the authors speculate that the sheer size of the natural lasers could make them useful tools in the future for communicating with distant civilizations beyond our own planetary system." The atmospheres of Mars and Venus are almost pure CO2 . The CO2 molecules are excited by the absorption of energetic solar photons; then, thermally emitted photons at about 10 micrometers from lower reaches of the atmosphere collide with the excited molecules, stimulating them to emit another 10-micrometer photon, thus doubling the number of photons. This is typical laser action. ...

"Sharply angular boulders as large as 320 kg [700 pounds] sit on the Racetrack Playa, Death Valley, California; trails leading to them indicate that the rocks have moved large distances. The process has never been witnessed. Although high winds and a wetted surface seem necessary, controversy persists about the need for other conditions, especially ice sheets.

He finds that these cetaceans tend to run aground at spots where the earth's magnetic field is diminished by the local magnetic fields of rocks. These coastal magnetic lows are at the ends of long, continuous channels of magnetic minima that run for great distances along the ocean floors. Kirschvink believes that the stranded whales and dolphins were using these magnetic troughs for navigation and failed to see the stop sign at the beaches and ran aground. The mag-netic troughs in this view are superhighways for animals equipped with a magnetic sense. If Kirschvink's theory is correct, the magnetic sensors of the whales and dolphins are extremely sensitive, because the deepest magnetic troughs are only about 4% weaker than the background magnetic field.

At a distance of 100 kilometers (62 miles), the flash was compared to that from an atmospheric nuclear explosion. Danish officials dismissed the possibility of a surreptitious nuclear test. The U.S .

In Iran alone there are about 37,500 qanats with an aggregate length of some 100,000 miles! Qanats rank right up there with the Inca roads and the Great Wall of China as wonders of the ancient world. After reading our catalog section on Iranian qanats, E. von Fange informs us that the qanats of Bahrain pose a set of different problems. The Bahrainian qanats are easy to follow across the desert because the access shafts protrude a few feet above the sand. As one follows them up-slope for a mile or two, some greenery appears in the distance---low bushes perhaps. A closer approach proves instead that the greenery is actually the tops of palms.

The bottom 14 terraces are built from rather small stones; but the top four consist of slabs weighing up to 2 tons. Trees as old as 600 years poke up through the stones, attesting to a pre-European origin. Another much larger pyramid inhabits dense scrubland near Sydney.

... But, ask evolutionists, how did this poison apparatus get on the hind legs? The supposed ancestors of the platypus, the reptiles, modified their salivary glands for venom delivery. How did the platypusses break from this evolutionary mold and innovate? It's not consistent with the text! The fossil record reveals that a platypus-like creature lived long before the Age of Mammals. These early platypusses had teeth in the adult phase, whereas their modern relatives replace their baby teeth with horny plates -- another innovation. Therefore, far from being a hodgepodge of parts left over from bird and reptile evolution, the platypus has actually pioneered several zoological features. Very curious is the fact that the platypus is in many ways like the beaver -- a very, very distant relative both in distance and position on the Tree of Life. Both platypus and beaver are furry, aquatic creatures with webbed feet and a large, flat tail. We have saved the strangest part for the end! Platypusses, being Monotremes (one-enders) have a common vent for waste and reproduction.
