Ice Typography is an environmental art series by Nicole Dextras displaying words made from ice on various landscapes.
This description is from her artist statement:
The installations have varied from 8-foot high ice letters on the Yukon River to 18-inch high letters set in downtown Toronto. When the ice texts are installed on site, the temperature determines how long it will take for them to change state from solid to liquid. This phase of transition becomes symbolic of the interconnectedness of language and culture to the land as they are affected by time and by a constant shifting and transforming nature.
