Finding Water in the Desert

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.
