24 percent of the land in the Northern Hemisphere has permafrost underneath it (Figure 1). So, permafrost makes up 23 million square kilometers (9 million square miles). Large expanses of permafrost occur in Siberia, the Tibetan Plateau, Alaska, the Canadian Arctic, and other higher mountain regions.

The length of what is left would be 1 1/2 feet long.
