What type of ice should you ensure is present before traversing on ice for safety?

• A. White ice
• B. Blue ice
• C. Gray ice
• D. Thin ice

Answer: (B)

Blue ice is the correct choice for ensuring safety when traversing on ice. This type of ice is typically more solid and consistent than other forms of ice, making it safer for walking or traveling. Blue ice is dense and often formed from the compression of snow or when water freezes under specific conditions, resulting in a strong and thick layer that can support weight securely.

In contrast, white ice tends to be less dense and is often formed from slushy conditions that freeze over, which can make it weaker and less reliable. Gray ice indicates the presence of water on top of the ice or ice that has begun to thaw, suggesting compromised strength and stability. Thin ice should be avoided altogether, as its fragility poses a significant risk of breaking under weight. Hence, blue ice provides the safest condition for traversing on frozen surfaces.
