Here's a few more caches that I've added to this open series started off by the Coast to Coasters.
James Brindley was the chief engineer of the canal and was constructed as part of his ambitious plan to connect Hull, Liverpool and Bristol.
The canal was completed in 1771 and opened to trade in 1772. It was a commercial success, with trade from the Staffordshire Potteries southwards to Gloucester and Bristol, and trade from the Black Country northwards to the Potteries via the junction with the Birmingham Canal at Aldersley.
The canal is 46 miles long so there's room for loads more caches.
Enjoy, I shall be adding some more myself.
