The Egryn Lights were unusual lights seen near the Welsh village of Egryn in the winter of 1904 which may offer a clue as to the nature of some reports of unidentified flying objects. According to one eyewitness: "Between us and the hills, apparently two miles away, there suddenly flashed forth an enormous luminous star with intensely brilliant white light and emitting from its whole circumference dazzling sparkles." Another said: "[It was] poised in midair, a mass of fire of every conceivable color spreading on all sides and descending into a rainbow shower to the surface of the mountain." Even more spectacular events were seen in the vicinity of some ancient megalithic remains in the neighborhood. From the ground, several multicolored columns of light sprang, two to three meters high. One of these appeared to flutter, as if there were some internal instability, and then started to produce spheres of light which slowly rose up its length before exploding at the top. It has been suggested that the people who once lived in these parts, over 3,000 years ago, may have witnessed something similar, and, interpreting it as a supernatural event, built stone edifices to mark the locations where the lights had appeared. It is at least an intriguing possibility that these and certain other prehistoric monuments were purposely erected close to where unusual, energetic events take place on the planet. And this, in turn, provides at least a plausible basis for the seemingly outlandish claims of a link between the flight paths of UFOs, currents of energy flowing in the earth, and the arcane knowledge of lost civilizations.
Drawing on reports from December 1904 to March 1905 of the lights near Egryn and also those seen several kilometers to the north and south, writer and independent researcher Paul Devereux plotted on a large-scale map the exact location of each sighting. He then sought the advice of professional geologists who pointed out the existence of a major, deep-seated fault, the Mochras Fault, running north-south between the coastal towns of Harlech and Barmouth and passing almost directly under the village of Egryn. When Devereux compared the places where the earthlights had been observed with the path of the fault he found a striking correlation: the reported sightings were strung out like beads on a thread. Checking the geological records, Devereux learned that the area had been subject to tremors immediately around and after the occurrence of the lights, culminating in a minor earthquake under the southern Welsh town of Swansea in 1906.1 Similar seismic activity in the Cascade Mountains may have been responsible for the "flying saucers" seen by Kenneth Arnold in 1947.
