Factors Affecting Ice Strength
The load-bearing capacity of ice is not solely determined by its thickness. Its strength can be significantly influenced by:
- Ice Age: Newer black ice is typically stronger than old, milky ice.
- Proximity to Shore: Ice closer to shore is generally weaker than ice farther out.
- Water Features: Ice near river inlets and outlets is weaker due to water flow.
- Subsurface Obstructions: The presence of rocks, trees, and plants can create weak points.
- Water Currents: Currents can erode ice from beneath, reducing its strength.
- Snow Cover: A layer of snow insulates the ice, slowing its growth and potentially adding weight.
Critical Safety Note
This information must only be used as a general guide. KEEP OFF the ice if you are not absolutely sure. Always consider local conditions, recent weather, and expert advice before venturing onto any ice surface.
