2-M Probe Survey:

Probe surveys are used to physically identify and delineate thermal anomalies. A 2-m long hollow steel tube with a tungsten-carbide alloy tip is driven into the ground using a hammer drill. Then a high-precision resistive-temperature device is inserted into the tube. The probe is then left in place for at least one hour.
