Abstract:
The invention is an apparatus and method of creating and preserving an outdoor frozen surface by covering a defined outdoor ground surface with a layer of white base paper after clearing debris, litter, and other objects from the defined surface which may present a hazardous condition on an ice surface. The layer of white base paper is saturated with water at near freezing or under freezing conditions to allow the water to freeze and hold the white base paper to the defined outdoor ground surface. Thereafter, water is continuously dispensed under freezing conditions to build up a predefined thickness ice layer on the defined outdoor ground surface.
