When spring arrives on the calendar, the frozen ground slowly begins to thaw from the bottom up, where it is more difficult for cold air to penetrate. As the month of April draws closer, the soil’s surface begins to thaw as well, and this process continues until both ends are completely defrosted. – Content Obtained From CBS Minnesota

How far down does the ground not freeze?
The depth of the line increases as one moves closer to either of the planet’s poles.

Does rain help thaw the ground?
According to Hill, prolonged periods of heavy rainfall can assist reduce the length of the mud season by hastening the rate at which the earth thaws.

How deep are footings in Minnesota?
In the absence of a judgment by an engineer with expertise in soil mechanics, the minimum permitted footing depth in feet due to freezing is five feet in Zone I and 3-1/2 feet in Zone II. In Zone III, there is no minimum allowable footing depth owing to freezing.
Is the frost out in Minnesota?
