Quicksand is a colloid hydrogel consisting of fine granular material (such as sand, silt or clay), and water. Quicksand forms in saturated loose sand when the sand is suddenly agitated. When water in the sand cannot escape, it creates a liquefied soil that loses strength and cannot support weight. Quicksand can form in standing water or in upwards flowing water (as from an artesian spring).
Quicksand typically has a density of 125 pounds per cubic foot (2 g/cm 3). This means you can float on quicksand more easily than on water. First thing you should do is drop your bags or gear. The less weight you pull, the better. Also, try pulling off your shoes as these create friction when you try to pull out of the quicksand.
