This was probably a hoax, or something overheard in a bar or on the street by a reporter that was meant as a joke or gossip.
Readers today think that the newspapers of the 19th century abided by the same standards of today's newspapers. Not so.
Samuel Clemens (Mark Twain) admitted later in life that he'd written more than a few "whoppers" as a reporter in Nevada and California, or embellished local news, to entertain readers and increase circulation. Editors and owners would expect this sort of thing.
This is precisely WHY old newspapers and accounts are among the poorest sources.
I've read newspapers as old as 1876, and it's amazing what goes into them.
I have a 1903 copy of an American newspaper that reports on the Army's new 1903 Springfield rifle and .30-caliber cartridge. It boasts how it will outrange the German Mauser by manyfold, and its cartridge (.30-caliber, 220 gr. bullet) can penetrate over 40 men in a line. Nonsense. It might penetrate 3 or 4 bodies at point-blank range, but not over 40.
And in truth, the .30-03 cartridge of that time had a lesser range than the German Mauser 7.9mm cartridge.
It's all propaganda.
I've never believed in the Devil's Footprints reports of 1855, because I'm well aware of the state of journalism at that time. If you think today's journalism is bad -- and it is -- it was far, far worse in the 19th century when it was absolutely unquestioned and most readers had little more than a rudimentary education, if any education at all.
Aaaah, I see.
Probably a hoax then. Might go hunting on Google to see if there's any reports of Devil's Footprints in today's time.
