Hmmm, speaking of Cracked - The Five Most Spectacular Landscapes (That Murder You)
I have already used both the Bolton Strid and the Corryvreckan Maelstrom in steampunk games. The Bolton Strid looks so... innocent
Does this look like a killer stream to you?
This is what it looks like, not too far upstream, where it is known as the River Wharfe:
See how wide it is?
Now turn it sideways and balance it on edge - that is the Strid... and it runs very quickly over a series of underwater caves.
No one knows just how deep it really is, but it is a killer....
