It took a while for firefighters to figure out which of the eight silos he was in. This is what happened to a man who fell into a grain silo in Germany in 2002. These grains don’t even need to be sand to have this effect. Once the dry sand or other grains solidify again around you, they can restrict air flow to your lungs. This is because it behaves in much the same way that snow in an avalanche does. The Danger of Dry Quicksandĭry quicksand is much more dangerous than wet quicksand. Especially if you are wandering around on sand or mud at low tide, where fine particles, salt, and sand mix. You are much more likely to find quicksand near bodies of water. Sometimes there are large air gaps in desert sand, but this isn’t common.Īfter a sandstorm, you are most likely to encounter desert quicksand. In pools of water where drainage is reduced by an underlying layer of non-permeable material, like clay.ĭespite what cartoons might have you thinking, deserts are not likely places to find quicksand.Springs that rise up in sand on beaches and riverbanks at low tide can cause quicksand. Near upwardly moving water, such as underground springs.RELATED How To Make A Camping Tent From Scratch: An Emergency Shelter, or For Fun Where Is Quicksand Found? This means that if the sand is agitated-by movement, upward motion of water, or vibration-the fragile structure collapses and becomes fluid.Īll that’s holding the sand grains together is friction, and when movement destabilizes the sand grains, quicksand is the result. In quicksand, these voids comprise from 30 to 70% of the mass of the sand. Sand normally has voids that make up 25 to 30% of its mass. It looks normal and safe to step on, but it is not. Quicksand is sand that has larger than normal gaps between the grains. Movement caused by people, earthquakes, or vibrations turns the quicksand from a solid to a liquid very quickly. When mixed with water or air, this creates gaps, called voids, in the sand. Quicksand is found in areas where there is fine sediment, like sand or silt. It’s the stuff of movies and childhood tales, but is it real? Where is quicksand found, and how can you find it? Picture this: an adventurer venturing into the unknown, the ground suddenly shifting beneath their feet as they sink into a perilous trap.
