Source of The River Eden Studies

In 2015, my brothers and I swam the 145 km / 90 mile length of the River Eden from source to mouth in 9 days. The source itself is located in North Yorkshire, and we trekked up to Hell Gill to find it. It turned out to be a bubbling mount of mossy earth, belching forth the River Eden, and it was from this point that we began our swim.
