Oh I forgot some Cavalry units traveling south and a distance east of Crowley's Ridge said they came upon a gaint earthen snake. When they rode their horses upon it, they saw it was the unfinished roadbed of the Memphis & L.R. Railroad. I don't when this was but I think it was Union troops. This comes from a book I read several years ago. Somebody wrote a good published article on the Memphis & L.R. R.R. a few years ago. I'm not sure what it was in, maybe North South Trader??
