When walking on ice, use the old BSA rule for ice safety:

1 inch, keep off.
2 inches, one may.
3 inches, small groups.
4 inches, O.K.

Some additional safety and rescue tips:

  • For the backcountry hiker who must cross that river with one inch of ice, get down flat on your belly and crawl across the ice. The more distributed your body weight is, the less chance you have of breaking through.
  • Ice on lakes and rivers is completely different. River ice has many more variations in thickness due to current.
  • Beware of ice near mouths of inflowing streams, streams flowing out of lakes, or near springs.
