We consider the problem of formation of a snow-firn 
stratum in a mass of snow. We assume that initially on the surface 
melt water is formed, which subsequently seeps through a porous medium 
and crystallizes due to cooling. The change in the porosity during 
the crystallization of the water in the mass of snow is analyzed.
