Yeah, I've seen pics/discoveries like this before in the UK. But, the article seems to be announcing a bonanza of new sites being easily visible. I find that exciting. I was always a big fan of archeology, moreso the anthropological aspects of it and how people lived, what their culture was like, etc.
Anyway, it's darn cool stuff. I'm an 'Murican... So, our "archeological" stuff is limited to ancient Indian monuments, arrowheads, some pottery, a few preserved bits and pieces where humidity just plain "doesn't go" and some interesting Viking stuff that people constantly argue about. So, while there are a few ruins to discover that can be a couple of hundred years-old, they don't quit have the possibility of having hosted ancient battlegrounds with "Knights in Shining Armor" brutalizing the populace. Best we can do is a few old blankets coated in smallpox...
A secret joy of mine: "Prehistoric battlefields" They're just so damn few confirmed ones to be able to figure out wtf was going on.
Where are the darn giant-ground-sloth-shock-cavalry!
Sure, they're slow... But, when they get there, wooo boy, watch out!
