Quick Answer
When searching for water under ice, use a thermal imaging camera to detect surface temperature anomalies, probe with a long-handled ice auger to locate areas of reduced ice thickness, and then use a chainsaw or ice saw to create a hole for further exploration.
Detecting Water Anomalies
To locate water under ice, first use a thermal imaging camera to scan the frozen surface. This technique takes advantage of the different thermal signatures of ice, snow, and water. Areas of water will appear as warmer anomalies on the camera’s display. Be cautious, as even small bodies of water can appear as significant temperature anomalies.
Probing the Ice
Once you’ve located a promising area, use a long-handled ice auger to probe the ice. Insert the auger at a 45-degree angle and twist it slowly until you feel resistance, indicating reduced ice thickness. Mark the location with a GPS device or a piece of tape, then move to the next area. For areas with thick ice, try probing every 10-15 feet to ensure you don’t miss a hidden body of water.
Creating a Hole
After identifying a likely location, use a chainsaw or ice saw to create a hole. Cut a circular hole about 12-18 inches in diameter, then use a hand auger or ice chisel to widen the opening. Be cautious when removing the ice, as the water pressure may cause the hole to expand rapidly. Once you’ve created a hole, use a water purification system or boil the water before drinking to ensure safe hydration.
