  Dry quicksand - Wikipedia, the free encyclopedia
Dry quicksand is loose sand whose bulk density is reduced by blowing air through it and which yields easily to weight or pressure.
Until recently, the existence of dry quicksand was doubted, and the reports of humans and complete caravans being lost in dry quicksand were considered to be folklore.
In nature, dry quicksands may evolve from the sedimentation of very fine sand after it has been blown into the air and, if large enough, might be a threat to humans.

Quicksand forms when water saturates an area of loose sand and the ordinary sand is agitated.
Quicksand can be formed by standing or flowing underground water (as from an underground spring), or by earthquakes.
Objects in the liquefied sand sink to the level at which the weight of the object is equal to the weight of the displaced sand/water mix and the object floats due to its buoyancy.

Quicksand, instead of being solid and dependable like the earth "should be," is a betrayal of our belief in the firmness of the ground beneath our feet.
For dry sand, or sand that is not too wet, the frictional forces between the particles are large enough to cause the sand to be relatively solid.
The primary characteristic of quicksand that sets it apart from ordinary sand is that the water pressure beneath the sand is equal to, or is slightly greater than the weight of the sand particles.
