Ice Safety Fundamentals
Ice Thickness Guidelines
Ice Assessment Protocol
Never assume ice is safe based on appearance alone. Clear blue ice is strongest. White opaque ice contains air bubbles and is weaker. Grey ice indicates water saturation and is unsafe.
Check ice thickness every few steps when first venturing out. Use an ice chisel, auger, or drill to make test holes. Ice thickness varies across any body of water due to currents, springs, and varying depths.
Avoid ice near shores, around structures, in areas with current, and near inlets or outlets. These locations experience different freezing patterns and often have thinner ice than open water areas.
Essential Ice Safety Equipment
- Ice picks worn around neck for self-rescue
- Throw rope at least 50 feet long
- Personal flotation device worn under outer layers
- Ice chisel or spud bar for testing
- Whistle for signaling distress
- Cell phone in waterproof case
If You Fall Through Ice
Remain calm and control breathing. Cold shock can cause hyperventilation.
Turn toward the direction you came from—that ice supported your weight.
Use ice picks to pull yourself onto the ice surface.
Kick legs while pulling to get horizontal and distribute weight.
Roll away from the hole rather than standing immediately.
Seek shelter and warmth immediately. Hypothermia risk is critical.
