We were recently filming in Nevada, USA, visiting interesting high dry and cold climate systems. We went out in search of a salt pan to film as a specific landscape feature.
Whilst on our journey we came across a large sand dune. It was a mighty Erg, an Erg is a wind blown mountain of sand that resembles a sand dune and they have a classic ability to hold moisture as fresh sand filtered water.
The phenomena, that most people don’t realise, is that fresh water sits on top of salt water. As with Swales, when we rehydrate the landscape with rainwater harvesting earthworks, we perch fresh water shallow aquifers on top of salted aquifers.
In this short clip Geoff explains how to find water in the natural spring line that sits down hill from the Erg.
Thank you, Geoff, for this and all your videos. They are educational, highly inspirational, and enjoyable to watch. I have begun using permaculture techniques in my garden as a result of being inspired by your work.
Thank you Mr jeoff for this video you are a great teacher give me a hoop to change our live fore bitter according to permaculture i love you in allah
