(3,629 posts)Clay with the right water content can go from nearly solid to very plastic with great suddenness. He probably broke through a relatively firm but thin slightly dryer surface layer.

http://www.turnagaintimes.com/SR09/Mudflats.html
Turnagain Arm mud consists of microscopic particles of glacial silt and powdered rock mixed with ocean water. Undisturbed, the mud is relatively solid and will support a fair amount of weight. However, if it is subjected to vibration, it quickly liquefies and anything on top of it rapidly sinks below the surface.
When a person sinks below the mud, the air around the body is displaced and any attempt at removal creates a suction that is nearly impossible to overcome without help.
