The maximum frost depth observed in the contiguous United States ranges from 0 to 8 feet (2.4 m). [1] Below that depth, the temperature varies, but is always above 0 °C (32 °F). Alternatively, in Arctic and Antarctic locations the freezing depth is so deep that it becomes year-round permafrost, and the term "thaw depth" is used
The list of snowiest places in the United States by state shows average annual snowfall totals for the period from mid-1985 to mid-2015. Only places in the official climate database of the National Weather Service, a service of NOAA, are included in this list.

The term itself is borrowed from the notion of "frost line" in soil science, which describes the maximum depth from the surface that groundwater can freeze. Each volatile substance has its own frost line (e.g. carbon monoxide, [ 1 ] nitrogen , [ 2 ] and argon [ 3 ] ), so it is important to always specify which material's frost line is referred ...

Permafrost temperature profile. Permafrost occupies the middle zone, with the active layer above it, while geothermal activity keeps the lowest layer above freezing. The vertical 0 °C or 32 °F line denotes the average annual temperature that is crucial for the upper and lower limit of the permafrost zone, while the red lines represent seasonal temperature changes and seasonal temperature ...
