Comparative study of the pollen and spores in massive ices of Subarctic region and from ice and snow cover of Arctic ice caps has been done. It is shown that some typical components of tundra and ground ice pollen spectra have never found in the ice and snow cover of Arctic glaciers. They include pollen of cloudberry, aquatic plants and spores of horse tail and green moss which are not adaptated for wind transportation. It has been demonstrated that the pollen spectra of glaciers are characterized by the dominance of far transported tree pollen such as pine, spruce, fir, maple, ash, oak, and also several herbs such as sage, ambrosia.

Key words: Massive ice, local pollen and spores, Yamal Peninsula, Arctic ice caps, far transported and exotic pollen, Russian and Canadian Arctic.
