Permafrost is the term used to describe a frozen layer of soil that remains below the surface layer of topsoil.
In the summer, the soil thaws to some depth below the surface, but the water is trapped in the thawed soil because the permafrost zone is impermeable. Thus solifluction occurs only in the summer when the surface soil layer is thawed. In the winter the surface soil layer is frozen solid.
