n. — Outdoors
a form of prism-shaped melting ice (see Image 1).
Type: 5. Frequency — Candle ice, which in older sources is sometimes called candle (see the 1796 and 1913 quotations), is slightly more frequent in Canada than in the UK, which suggests a connection through early British explorers. In light of Canada's colder climate, it may be culturally significant in some parts of the country.
