Abstract: A method of building ice structures using guidelines attached to posts to form a framework. Water is sprayed on the frame from sprinklers. Ice forms on the guidelines and grows until the ice supports itself. The structures are built higher as guidelines are added above each previous row of ice. As the ice continues to build up over time, the structures grow in height and thickness to be strong, freestanding structures. The method for creating ice pillars involves the following: Installing vertical posts, positioned around a sprinkler; attach guidelines from post to posts, creating a framework; and spraying water at low temperatures causing ice to form on framework. If desired height of pillar has not been reached, raise sprinkler and attach new guidelines above previous guidelines to existing posts. If desired height has been reached but desired thickness has not, continue spraying water at low temperatures.
