Which of the following is NOT a type of ice listed?

• A. Frazil
• B. Clear
• C. Candled
• D. Go

Answer: (D)

Understanding ice types helps you assess safety on frozen water. Frazil ice appears as loose, needle-like crystals in fast-moving water and is very weak, forming before a solid sheet develops. Clear ice is a strong, solid sheet that forms when water freezes slowly and air bubbles are expelled, giving it a transparent appearance. Candled ice forms with vertical channels or “candles” due to particular freezing patterns and trapped air or brine pockets, making it weaker and more hazardous than smooth clear ice. The term that isn’t a recognized ice type is “Go,” so it isn’t used to describe ice conditions.
