Finding Water in the Desert (Nevada) with Geoff Lawton

https://www.youtube.com/watch?v=owlVLwEB11o

Before taking Geoff Lawton's online PDC, I never realized that very large sand dunes actually have a lens of water in them. Due to the pressure of the weight of the sand, moisture will seep out of them on the downhill side allowing wells to fill and greenery to flourish.

And Geoff gives me another piece of the puzzle!

The largest moving sandunes in the US are called the Killpecker sand dunes. They cover a vast area of Wyoming. Here are a bunch of pictures of the area.

If you look through the pictures you can see many that show the water and plants .
I knew that there was a lot of water under the area, and there are many old homesteads out there because of it.
A couple of folks I know, who study these sorts of things, told me that as the sand blows up and over a dune, in the winter, it will swallow up snow drifts. These snow drifts form large "ice drifts" and stay inside the dunes for many years. As the sand keeps moving the ice reappears and begins to melt forming water holes all over the place. Now Geoff has added another interesting bit of knowledge that would apply there. These dunes may not be as tall but they do have an affect on the landscape around them.

Plants that indicate ground water

This report was not easy to find. For folks interested in survival or in finding suitable locations in arid or semi-arid climates.

Thanks Socrates, that will keep me busy reading for a while !
