Well they certainly didn't post the best pics possible of it, but nevertheless what I could see was indeed very, very interesting.
'I heard this rushing like Niagara Falls,' he said. 'And I could see this water wearing away the land. The field was perfectly flat 25 acres before. Now there's only about 18 acres left.
'It's an amazing phenomenon, but I estimate it's the result of water from up to 120 acres of flooded land.'
(Emphasis added by me)
The photos from the article show a winding water path that-yes-looks like a canyon... but only 6 or so feet deep. I'm originally from Texas and very familiar with flash-flooding. Without a prior channel being there, that should've just skimmed the top off that field as all the water flowed across the "perfectly flat' terrain. If there had been even a small gully there it would've certainly got dug out deeper by the flow, but without the depth/width necessary to contain the volume of water, it would've washed out quite a swath to either side of it's banks.
Here's what I saw from the photos:
1. Steep walls of an almost even height,
2. Very little undercutting of the outer banks of curves, little or no slope on the inner curves,
Items 1 & 2 make me think of some kind of electrical excavation or rille, but...
3. The trickle of water down the middle of the ravine is meandering from inside curve to outside following 'path of least resistance' rather than following a deep cut down the center like you would expect of a rille,
4. The walls were collapsing, indicative that the surrounding earth became extremely saturated to quite a depth. A flash flood would not do that, so the ground had to have been pre-saturated. Water flowing over muddy ground will certainly behave differently than water flowing over dry ground with higher adhesion characteristics.
I think the jury is out on this one, as odd as it sounds. I'm not about to completely rule out electromagnetic effects, however. As many people have stated- water behaves as a sort of pseudo-plasma. It's entirely possible that the flow of the water through this area was affected by telluric currents in the field which might've caused more cohesion of the flow of the water itself, even if electric currents didn't do a big batch of excavating prior to the torrent running through that field. I noted in one of the pictures in the article that there was an irrigation pipe buried perpendicularly to the ravine at about half it's depth. On the right side of the picture you'll see that there is a cutout in the channel that heads in the direction of the pipe itself. Could the iron piple have affected the electromagnetic field and pulled some of the volume along it'se length?
Difficult to tell from the perspectives of the few pictures presented in the article. It's worth keeping in the file drawer tho, I think!
