While it isn’t possible for a person to sink entirely in quicksand, that doesn’t mean it isn’t dangerous. However, panicked movement causes a person to sink further and makes extraction by the victim or a rescuer more difficult. At that density level, you would only sink in to about your waist. Quicksand has a density of about 2g/mL, while the density of the human body is only about 1g/mL. Objects in quicksand sink to the level at which the weight of the object is equal to the weight of the displaced quicksand. A person will start to sink when they step on quicksand, but even a person moving in quicksand will never sink all the way as the human body isn’t dense enough. The higher the stress, the more fluid it becomes. It is not usually a problem at Zion, but quicksand can form there when there the conditions are right.Īt rest, quicksand appears solid, but it becomes unstable when exposed to a sudden shock or stress, like the weight of a hiker. Quicksand is a mixture of sand or silt and water that is typically found on riverbanks, near lakes, in marches, or near coastal areas. ![]() In reality, quicksand doesn’t suck people under the way it always seems to in the movies, but it is difficult to get out of and can be extremely dangerous. We’ve all seen the action films where quicksand swallows its victims whole. Thankfully, both hikers recovered fully from their misadventure. They had to spend the night out in the park until a helicopter crew was able to extract them the following day. ![]() A search and rescue team found the second hiker several hours later, but they were not able to free him from the quicksand until late into the night. After hiking alone for hours, the first hiker was finally able to call for help. There was no cell service in the area and with no chance of extracting the second hiker on her own, the first hiker was forced to leave the second hiker with their warm weather gear and head out in search of help. He was not only stuck in the frigid quicksand, but also exposed to the elements. The first hiker was able to escape, but no amount of effort from either of them could pry the second hiker loose. Two hikers were recently hiking the remote Subway Trail in Zion National Park, Utah, when, believe it or not, they became trapped in quicksand! The first hiker stepped in the colloid suspension and when the second hiker attempted to rescue her, he too became caught and buried up to his knee. ![]()
