Quick Answer
Traveling on ice after a heavy snowstorm is not advisable due to the increased risk of collapse. The ice may be weakened by shifting water beneath, and the snow cover can hide cracks or uneven surfaces. It's best to wait for a few days or until ice thickness meets safe guidelines.
Assessing Ice Thickness
When considering travel on frozen lakes or rivers, it’s essential to assess the ice thickness. A minimum of 4 inches (10 cm) of clear, dark ice is generally considered safe for walking, but this can vary depending on the water below and the presence of snow cover. For vehicles, a minimum of 8-12 inches (20-30 cm) of ice is recommended. To determine ice thickness, use a tape measure or a drill to collect a core sample and check its depth.
Recognizing Hazards
Heavy snowstorms can create unique hazards when traveling on ice. Snow cover can hide cracks, uneven surfaces, and other obstacles, increasing the risk of accidents. Look for signs of weakened ice, such as cracks, dark spots, or unusual coloration. Be cautious of areas with a history of flooding or water flow, as these areas are more susceptible to ice collapse. Always travel with a buddy and stay alert for potential hazards.
Safe Travel Techniques
When traveling on ice, use safe techniques to minimize your risk. Travel in groups to provide mutual support and assistance. Stay on the ice surface and avoid walking on the edges, where the ice is more prone to collapse. Wear proper clothing, including warm, waterproof gear and sturdy footwear with traction. Keep your weight centered and avoid sudden movements, which can cause you to lose balance.
