I was recently reading about the Bolton Strid,a very innocuous looking booby trap in England.
The Wharfe river is abruptly reduced in width at this point,and the banks are severely undercut by the swift and deep water.
Anyone that falls in is never seen again.
There are caves and cilff faces under the banks,according to the article I read,and this strid has been there thousands of years.
It seems like this would be a paradise of lost bones of people and animals,akin to the tar pits.
Has anyone explored this area with ground penetrating radar,or a tethered robot and camera?
