The North Dakota Game and Fish Department cautions hunters to be wary of ice conditions.

In some parts of the state, there are smaller waters that show the appearance of safe ice. Hunters should be cautious of walking on frozen stock ponds, sloughs, creeks and rivers.

Ice can form overnight, resulting in unstable conditions. Ice thickness is not consistent, as it can vary significantly within a few inches. Hunters walking the edge of a cattail slough will not find the same ice thickness in the middle, as the edges firm up faster than farther out from shore.

A few reminders:

• Snow insulates ice, which in turn inhibits solid ice formation, and hides cracks, weak and open water areas.
• Avoid cracks, pressure ridges, slushy or darker areas that signal thinner ice. The same goes for ice that forms around partially submerged trees, brush, embankments or other structures.
• Daily temperature changes cause ice to expand and contract, affecting its strength.
