Sand Blow Charcoal

Carbon dating of the charcoal excavated with back hoe from a sand blow was 40,000 years BP. Gray material is from the water-perching gleyed horizon.

1811-1812 New Madrid Earthquakes
“In all the hard shocks mentioned, the earth was horribly torn to pieces - the surface of hundreds of acres, was, from time to time, covered over, in various depths, by the sand which issued from the fissures, which were made in great numbers all over this country, some of which closed up immediately after they had vomited forth their sand and water, which it must be remarked, was the matter generally thrown up. In some places, however, there was a substance somewhat resembling coal, or impure stone coal, thrown up with the sand. It is impossible to say what the depths of the fissures or irregular breaks were; we have reason to believe that some of them are very deep.”
