British fact-seeker Tom Scott offers a reasonable explanation as to why the narrowest part of the River Wharfe is also considered to be the most historically lethal. Known as the Strid at Bolton Abbey in North Yorkshire, England, the water appears to be a tranquil stream with green mossy banks, however, the serene appearance belies the fact that its invisible fast moving current, lack of a riverbed and rocky sides have taken a number of lives.
There are certainly rivers that have taken more lives, and there are rapids and waterfalls that few boats could ever sail. But generally, you can see them coming. This is just an innocent looking stream in the middle of some woods. You could jump over it. People occasionally do. But if you miss that jump, it’ll kill you.
