Dangers of Pressure Ridges

pressure ridge

Several pressure ridges have been reported this winter on Lake Minnetonka. Pressure ridges are generally found on larger bodies of water and are formed due to temperature changes and ice pressure, winds, or currents pushing up the ice. It is recommended that you avoid crossing and keep an eye out for pressure ridges. One danger is falling through the thin ice or adjacent open water. Another danger is when the heaved ice is hit by people driving snowmobiles or other vehicles. Pressure ridges can be difficult to see especially if covered with snow or at night. Damage to property, injuries, and even deaths have been associated with pressure ridges so take precautions to stay safe!
