It is unusual as Mayan sites go because its 375 structures, including a large stepped pyramid, incorporate millions of fired bricks. Many of said bricks, when separated from their mortar, display various symbols as well as their makers' fingerprints. N. Steede collected a "small" sample of these bricks (4612 bricks weighing in at 21 tons) and photographed the inscriptions that decorated some 1,500 of them. Many bear what are interpreted as "masons' signs". These turn out to be virtually identical to those found on Roman bricks in the Old World. Conclusion: "The illustrated bricks of Comalcalco are pieces to a grand puzzle, whose completed, final image may reveal a Roman Christian presence in the Americas a thousand years before the arrival of Columbus."

Navy began operating a 90-kilometer-long radio antenna stretching pole-to-pole through a Michigan forest. Broadcasting at only 76 hertz, this long antenna can communicate effectively with submerged submarines. Although the antenna produces electromagnetic fields about the same as those from a large household appliance, some of the trees adjacent to the antenna have enjoyed an unexpected spurt in growth, according to D. Reed and G. Mroz of the Michigan Technological University. "The researchers have been gathering data on the growth of trees since 1985, making measurements at two sites, one near the antenna and the other 50 kilometers away. The results seem to suggest that the electromagnetic field has a subtle influence on the forest. They found that two species of trees, northern red oak and paper birch, do not seem to be influenced by the antenna at all. But red pines near the antenna grew taller than red pines at the distant site, while aspen and red maple grew thicker than their counterparts further off."

The burial has been dated as from the 12th-13th centuries AD. The features of this little head can hardly be described as typical of Precolumbian Mexicans. In fact, it is often termed a "Roman" head. But is it really? And how did it get into a Pre-columbian burial site? Theory #1 . Some Mexican archeologists insist it is a post-Columbian artifact that somehow "filtered" down into a Pre-columbian site. Given that the head was retrieved from beneath three floors of stone and Indian cement, this theory seems questionable. Theory #2 . The head is truly of Roman origin and was transported to Precolum-bian Mexico from Southeast Asia by Chinese or Hindu voyagers. Theory 3. The author of the present article, R.H . Hristov, favors a Viking origin. The cap on the head and even the physiognomy have Norse overtones.

The heat brought to the surface via this plume has created the volcanic chain as the surface plate has drifted over it during the past 73-or-so million years. Obviously, this model is starkly contradicted by the fossil plume under South America (described above) that seems to have been firmly attached to the South American plate for 120 million years. No differential motion there! Now, from a different line of evidence, P.D . Ihinger is challenging the well-entrenched "Hawaiian-volcanic-chain" theory. For example, the Hawaiian volcanoes do not line up exactly. There are dozens of short, overlapping segments rather than a continuous trace across the Pacific basin. On the map, you will also see a sharp dog-leg in the trace. Further, the volcanoes Mauna Loa and Mauna Kea, only 40 kilometers apart, disgorge lavas that are distinctly different. Something is not right! Ihinger postulates a strong mantle current flowing ponderously under the Hawaiian chain, dissecting the rising plume of hot rock into small "plumelets". These discrete blobs of hot rock are dispersed by the current of semi-solid rock ...

"We can only assume that Feynman was not really trying, since when we investigated this profound and fundamental problem in our own kitchen laboratory, not only did we quickly establish the underlying mechanism, but we even went on to formulate the following general rule for linear spaghetti structures:- If a spaghetti stick is uniformly bent until it fractures and ejects a third piece, then the third piece is always ejected outwards from the convex side. "When the spaghetti fractures for the first time, the two remaining pieces then spring outwards, and providing there is a sufficiently weak potential fracture site on the opposite side a second fracture occurs, resulting in a third piece being ejected away from the initially convex side."

As many as 200,000 pine and fir trees had to be cut down and transported as much as 50 miles, for no sizable trees grow near Chaco Canyon today. There is no consensus as to where all these trees were felled. S. Durand, an archeologist from Eastern New Mexico University, Portales, has developed a technique for identifying the sources of logs. He tries to match trace elements in the Chaco Canyon logs with those in living trees in today's forests. The different bedrocks underlying the various forests supply different quantities of such trace elements as barium and manganese. Preliminary results suggest that the early building period in Chaco Canyon, circa 900 AD, employed trees from many different sites. During the peak building period a century later, all logs used carried the same concentrations of trace elements and, therefore, probably came from the same forest. Durand's next step is to locate this forest and figure out how the builders of Chaco Canyon, the Anasazi, managed to tote the logs, some weighing 600 pounds, 50 miles or more.

These plastic-like coatings are produced by bacteria and fungi. Sure enough, microscopic examination of a few linen fibers from the Shroud of Turin show that they, too, are coated with such varnishes. These biogenic varnishes may introduce carbon that has been recently fixed from the atmosphere and thus make the sample's age appear younger than it really is. (Travis, John; "Microbes Muddle Shroud of Turin's Age," Science News, 147:346, 1995.) Comment. More than the Shroud is at stake here.

The effectiveness of the method is still highly disputed. Now, however, extensive field studies -- in line with provable and reliable historic account -- have shown that a few carefully selected dowsers are certainly able to detect faults, fissures and fractures with relative alacrity and surprising accuracy in areas with, say, crystalline or limestone bedrock. A series of Deutsche Gesellschaft fur Technische Zusam menarbeit (GTZ) projects involving this technique were carried out in dry zones with unexpectedly high rates of success. In particular, it was possible to locate a large number of relatively small underground aquifers in thinly populated areas and to drill wells at the sites where water is needed; the yields were low but sufficient for hand-pump operation throughout the year. Finding or locating a sufficient number of relatively small fracture zones using conventional techniques would have required a far greater work input."

Local residents have known about the mounds for years, but archeologists weren't attracted to them until clear-cutting of the trees in the 1970s made the size and novelty of Watson Break all too obvious. Just how anomalous is Watson Break? Archeologist V. Steponaitis, from the University of North Carolina, opined: "It's rare that archaeologists ever find something that so totally changes our picture of what happened in the past, as is true for this case." On what does Steponaitis base such a powerful statement? Watson Break is dated at 5,0005,400 BP (Before Present), some three millennia before the well-known Moundbuilders started piling up earthen structures from the Mississippi Valley to New York State. In other words, the site is anomalously early. Indications are that Watson Break was built by hunter-gatherers, but no one really knows much about them; there's an aura of mystery here. Watson Break consists of 11 mounds -- some as high as a two-story house -- connected by a peculiar circular ridge 280 meters in diameter.

The underlying premise is that the peoples who constructed Stonehenge, Avebury, and other megalithic sites had a penchant for aligning them, even when they were separated by many miles. Exactly why anyone would wish to go to such trouble escapes the modern mind. American archeologists generally eschew ley hunting, but S. Lekson, from the University of Colorado, was surprised to find that three important Anasazi sites in the Southwest are actually aligned with high precision along Longitude 107 57'. The three sites are: Aztec Ruins and Chaco Canyon (New Mexico) and Casas Grandes (Mexico). Even though the first and last are separated by about 450 miles, all sites are within 1 kilometer (5 /8 of a mile) of the north-south line. Lekson maintains that an alignment this precise cannot have happened by chance. How could the Anasazi have achieved such an accurate alignment over such rugged terrain? It would not be easy even with modern transits. (Cohen, Philip; "One Dynasty to Rule Them All," New Scientist, p. 17, December 14, 1996.) Comment.

A casual observer of this huge earthen structure could only conclude that such immense labor was undertaken for some social imperative, such as worship or sacrifice. Perhaps this was the case in North America, but deep in the South Pacific, just east of Fiji, on the islands of Tonga, native peoples scraped large mounds of earth for what seems to be a frivolous purpose: pigeon-snaring ! But bear in mind that carnivory on these romantic Pacific islands was difficult because large game animals were nonexistent. Captured enemies helped solve the protein problem, but pigeons were much more common, and some species were good-sized and delicious. So much so that eventually only island royalty was allowed to catch and eat them. Pigeon poachers were whipped or executed (and maybe eaten?) In fact, pigeon snaring became a royal sport. To this end, starting at least a thousand years ago, the king's loyal subjects grubbed up the thin island soil and piled it up into high mounds. Tonga's pigeon-snaring mounds did not compete with Monk's Mound sizewise, being at most 115 feet in diameter and perhaps 15 feet high. But ...

(SF#101) Geologists classify these slides as either "slumps" or "debris avalanches." Slumps move just a few inches a year but are prone to bigger, jerky adjustments. Debris avalanches are fast cascades of rocks and soil. In Hawaii, both varieties of movement can involve massive blocks of real estate. In the huge Nu'uanu debris slide, stone blocks 6 miles across tumbled 30 miles out to sea. Both slumps and debris slides may create colossal tsunamis. (Tsunamis are miscalled "tidal waves," but they have nothing to do with tides and do not behave like tides or wind-driven waves.)

This will have to come later. These "circles of contention" are engraved on tall boulders (about 2 meters high on average) arranged in arcs hundreds of meters long at a site the aborigines call Jinmium. Jinmium is located near the western boundary of Australia's Northern Territory. The circles are obviously the work of humans. There are thousands of these etchings all told. Dimensions: 2-3 centimeters across and about half as deep. No one doubts that the Jinmium site is ancient. Judging from the sediments that cover the lowest circles, these engravings are about 60,000 years old.

... Lunar Landslide Lights Moonwatchers have reported light flashes, strange red glows, and mist-like patches emanating from certain lunar locales, particularly the huge craters Alphonso and Picard. Hundreds of such observations have accumulated since the Middle Ages. Modern more-systematic scrutiny indeed confirms that the moon is not such a dead place after all. (See ALF in The Moon and the Planets for much more on this fascinating subject.) Moonquakes, gaseous emissions, and even volcanic activity have been the favorite explanations of these TLPs (Transient Lunar Phenomena), but these are only surmises. The many close-up photos of the lunar surface taken in 1994 by the lunar satellite Clementine gave B. Buratti, K. Herkenhoff, and T. McConnochie the opportunity to search for geological common denominators connecting the sites where TLPs have been most frequent. The suspicious sites are characterized by bluish spectra that usually indicate unusually fresh deposits of lunar debris. Furthermore, these areas are usually found along the inside edges of large craters. Buratti et al opine that these are the sites of recent landslides that have cascaded off the crater edges. The dust and volatile gases released by these events might account for the observed luminous phenomena. (Cowen, Ron; "Explaining a Lunar Mystery," Science News, 150:314, 1996.) Reference.

Picking up the gauntlet, several more-conservative archeologists visited the Brazilian site and penned a blistering critique in Antiquity.

Superficially, it is a terraced earthen mound 100 feet high and more than three football fields long. What we now see of the mound was apparently constructed between 900 and 1200 AD. The prevailing dogma has long been that the Indians who built Cahokia worked only with earth, never with stone. Indeed, suitable stone is scarce in the area. On January 24, 1998, while drilling to construct a water drainage system at Monk's Mound, workers hit stone -- at least 32 feet of it -- perhaps a region of cobbles or slabs of rock. This region of stone, of undetermined geometry, is located 40 feet below one of the terrace surfaces, but still well above the base of the mound.

... 1997.) Once we learn how to measure neutrinos really well, we can start looking for intelligent signals impressed upon them by advanced extraterrestrial civilizations. W. Simmons and colleagues at the University of Hawaii at Manoa point out that neutrinos are much better than electromagnetic waves for galaxy-wide communication. They are not blocked by dust nor are they smeared out by ionized gas. Any civilization clever enough to colonize the entire galaxy would want to send out neutrino signals if only to keep clocks in far-flung star systems synchronized. Simmons et al calculate that a neutrino detector containing a cubic kilometer of seawater could probably detect neutrino signals from artificial sources located within 3,000 light years of earth. A detector that might be able to do this is being installed in the ocean off the Hawaiian Islands. Naturally, it has an acronym: DUMAND = Deep Underwater Muon and Neutrino Detector. (Chown, Marcus; "Do ETs Phone Home with Neutrinos?" New Scientist, p. 19, December 3, 1994.) Reference.
