As water is a necessary ingredient, deserts probably do not host any quicksand. In the old movies, quicksand was sometimes found in the desert. The saturated sediment that forms the surface will suddenly break and you will fall in. On top, i t will appear solid, and you won’t know what it is until you’ve put your weight on it with your foot. In some cases, the material, usually sand or clay mixes with the water and creates a kind of porridge. But sometimes, a pocket of water without drainage can form, or there can be streaming water under the surface, sideways, or upwards. Under normal co nditions, rainwater or sea water will sink through the soil to the groundwater level. Most common is still quicksand made from sand, slit, or clay, mainly because that’s what you would find in nature. Any granular material can in theory form some sort of quicksand-ish substance. But what is the truth about all that? What is quicksand and how does it form?įirst of all, it’s not only sand.
