Webb quoted: "The most startling is a report of an event in early 1490 in Ch'ing-yang, Shansi, in which many people were killed when stones "fell like rain." Of the three known surviving reports of this event, one says that "over 10,000 people" were killed, and one says that "several tens of thousands" were killed." Does anyone know where Ch'ing-yang, Shansi is in China? I ask this question because, unlike many of the other alleged meteorite falls reported to have caused either injury or death to humans, this fall, as reported, would have been extensive enough to have left behind some sort of "findable" physical evidence in the form of actual meteorites. Applying the basic principles of geomorphology, Quaternary geology, and site formation processes as developed by archaeologists, a well- trained Quaternary geologist, archaeological geologist, or geomorphologists should be able to locate the landforms and colluvial or fluvial deposits of the right age in which any of these numerous meteorites would have been concentrated and either them or their weathered remains possibly preserved For example, on landforms that predate 1490, the meteorites would have been buried by bioturbation. As the local soils were churned by farming and soil fauna, any meteorites that would have fallen on the land surface would have eventually sunk to the base of the soil's biomantle. As a result, they would be concentrated as a layer at the base of bioturbation called a "carpedolith". In gullies and other exposures, they would occur as a "stone line" at the base of the biomantle. Also, using what is known about the archaeology and geomorphology of the area, a person could locate the buried land surfaces or deposits of the right age and origin that should contain these meteorites, if they indeed exist. This is the sort of methodology I discuss in relationship to the alleged tektites found in Rapides Parish, Louisiana in "Reevaluation of Tektites Reported from. Rapides Parish, Louisiana" at either: http://www.lgs.lsu.edu/deploy/uploads/Summer_09_LGS_Newsletter.pdf or http://www.scribd.com/doc/18698759/Alleged-Tektites-From-Rapides-Parish-Louisiana A hypothetical stone line can be seen in "Animation on Dynamic Denudation/Biomantle Evolution" at; https://netfiles.uiuc.edu/jdomier/www/temp/biomantle.swf and discussed in: Johnson, D.
