My favourite subject! Solved my mystery of how and roughly where, the River Lea that runs through my town north of London originated. Springs and chalk bedrock. Extremely hard water here as well. Changing my dishwasher every 2 years… Thanks for another great video!!🙏
I like using Google Earth to follow rivers to their start point. It's so cool how a rapid river can start as a very slow trickle of water that melts off a glacier.
