Slush (snow)

Encyclopedia : S : SL : SLU : Slush (snow)

Slush is a slurry mixture of liquid and solid forms of water. In the natural environment, slush forms as ice and snow melts. This often mixes with dirt and other materials, resulting in a gray or muddy brown color. Often, solid ice or snow will block the drainage of fluid water from slushy areas, so slush often goes through multiple freeze/thaw cycles before completely disappearing. In areas where road salt is used to clear roadways, slush forms at colder temperatures than it would ordinarily, and only in salted areas; this can produce a number of different consitencies over the same geographical area.

"Slush" can also refer to the fat or grease that is obtained by boiling salted meat. This is where the term slush fund originated.
