The Web site mentioned in the article is complete trash and the "crater" is imaginary, as was pointed out years ago on this very List (not by me). Ken Rieli is a complete crackpot, and Mr. Wood appears to be a recent convert, although the newspaper article does not make it clear whether they even know of each other. But the fires are real and have been thought to require an explanation for a long time, even by non-crackpots. The literature on the subject goes back a long way. These strange fires were not restricted to the IL-WI-MI triangle centered around the southern end of Lake Michigan. Because of the slowness of communication in 1871, it was not immediately recognized that the fires of October 8, 1871 were scattered over parts of seven states and Canada and may have caused as many as 10,000 deaths. The scope of this disaster led a Minnesota Congressman, Ignatius Donnelly, to write a super-best-seller book called RAGNAROK shortly after the fires, in which he put forth the Comet Biela theory. RAGNAROK was so financially successful that Donnelly quit Congress to write more books including one in which he invents the modern whacko concept of Atlantis, a trick that made him even more money. So the first question is: does the simultaneous outbreak of a number of very bad fires over a large area after a dry summer require any special explanation? Common sense says no, hence the large number of responses going pooh-pooh to this retired engineer who's reviving a 130-year-old crackpot theory, with his own twist: frozen methane, which unfortunately for his theory will not start fires, but only create, well, you know what. However, the characteristics of these fires are so abnormal that from the very day they occurred they have been considered mysterious. Peshtigo was a town of mills and factories, 4 hotels, 15 stores, and 360 homes, and a total population of 2000 people. In minutes, 1152 people died. The conditions were hot, dry, and WINDLESS. The same conditions prevailed at all the sites of the 1871 fires. Stone buildings were reduced to calcinated ash. One large house was observed to burst into flame and rise 85 feet in the air on its own updraft. Large numbers of victims had no burns or injuries; they simply suffocated in the oxygenless air (a demonstration, by the way, that this was not a fire accelerated by wind). The largest number of survivors escaped into the woods surrounding the town (demonstrating that was not a forest fire). A total of nine towns in four Wisconsin counties were essentially exterminated at the same time. In one town of 260, the death rate was 100%; no one survived. What happened in Peshtigo remained a "mystery" until after World War II. All the evidence and survivor testimony suggests it was a "firestorm," a non-natural phenomenon which was employed as a weapon of war (once discovered by accident). The creation of a firestorm requires a concentrated stock of combustibles (a city), hot dry windless weather, and the simultaneous application of a large number, many thousands, of ignition sources. As a weapon of war, it is actually more devastating than nuclear weaponry (my opinion). "Successful" firestorm attacks in 1945 killed 85,000 people in Hamburg (the accident that, once explained, showed what a firestorm was), a quarter million people in Dresden, and nearly a million people in Tokyo. (Humans can always improve on things, can't they?) A firestorm is a multi-sourced fire so rapidly ignited over a large area of combustibles that temperature in the core region rises to thousands of degrees in minutes. The "updrafts" from this heat source achieve vertical velocities of hundreds of miles per hour. As a result, cool (heavy) oxygenated air from all directions is drawn inward at ground level at high speeds (50 to 100 mph) toward, but never reaching, the radiant core, the oxygen being totally depleted at the "firewall" or flame front before the core is reached. Firestorms spread upwind, that is, in all directions outward from the core, the "firewall" being the boundary between oxygenated and de-oxygenated air. The continuous influx of oxygen is the key; given enough radiant heat and oxygen, ANYTHING will burn. The mechanism is self-sustaining until every fuel source in the ever-expanding core (including the less familiar ones like stone, brick, some metals, and people) is exhausted. I'm not going to detail the more bizarre and Dantesque characteristics of a firestorm -- go read some history. But the key point for this discussion is the fact that a firestorm is not a natural phenomenon. It simply cannot happen unless human beings make it happen, as far as we know. The scale, speed, temperatures, and destruction produced by firestorms are without parallel in so-called "natural" events. They are an order of magnitude (or two or three) out of the ordinary. But so are the fires of 1871. Nothing like them has happened before or since, no matter how many "dry summers" there have been. Early attempts to start firestorms using only 2000 to 3000 incendiary devices dropped simultaneously failed. It takes 8000 (usually) or more. Interestingly enough, early nuclear weapons dropped on cities were not enough to get a really good firestorm going. So you can see how hard it is to start one. Peshtigo was overshadowed by the "Great" Chicago Fire (which happened at the same time) even though more people were killed at little Peshtigo than at Chicago. Careful examination of the reports indicates clearly that both "fires" were firestorms. In Chicago, a "solid wall" of fire advanced "upwind" in the face of a 40 mph wind (forced oxygenation and radiative acceleration), buildings blocks from any visible flames burst into flame instantaneously (radiative ignition), and ingots of iron stored on the banks of the Chicago river downtown melted and ran into the river (requires temperatures in excess of 2700 degrees F). These are all definitive of a firestorm. You can forget the one-cow theory. You can forget the 10,000-arsonists theory. In Peshtigo, the first event those who were awake agreed on was a blinding aerial flash, a thunderous detonation, hundreds or thousands of sudden little fires springing up everywhere, and the slow inrush of that terrible wind that turned their little town into a furnace in a time frame too brief for most of the inhabitants to escape. There are (but not universally) similar reports from everywhere these fires occurred. October 8 is the date of the now-weak Draconid meteor shower (or was in the 1870's). The source of the Draconids is Comet Giaccobi-Zinner. This comet was one of the first to be observed by a passing spacecraft. It's shape is a "pancake" whose equatorial diameter is five times its polar diameter. It is rotationally disrupted and material at the equator of the comet is virtually weightless. This disruption (which has to have been sudden and not progressive) has to have occurred very recently since the comet is dissipating rapidly and would be gone already if the disruption had happened very long ago. The radiant in Draconis is always above the horizon if you're far enough north. The terminus of the longest grazing path for Draconids (which would be the orbit of the heaviest fragments with the highest velocities) lies at 45 degrees north latitude (Peshtigo, Chicago, Michigan). A multitude of clusters of comet fragments air-bursting would produce a simultaneous barrage of Tunguska-like events with sufficient thermal output to produce numerous ignitions at ground zero. The date, 1871, is before the invention and deployment of either seismographs or barographs, so no evidence of these air-bursts would have been obtained as they were in the case of Tunguska. The case for the fires of 1871 has to be evaluated on the basis of the evidence. That's my "explanation" of the 1871 fires, scientifically feasible, I think, and boy! do I hate it when another crackpot comes along with an inferior crackpot theory, particularly when he stole his theory from a crazy dead Congressman! It makes all us crackpots look bad! On the other hand, isn't a story like "Citizen Steals From Congressman!" a little like the classic "Man Bites Dog!"? Sterling K.
