Did you know...? The T-shaped handle of the frost probe is used to push it into the ground until it suddenly stops. With experience, it may be possible to use the impact and the sound the probe makes to tell whether it has hit frozen ground or a rock. Frost probing at the end of summer that encounters frozen ground shows that permafrost is present and the depth of the probe tip is roughly equal to the active layer thickness.
