To compute the distribution of permanently shadowed areas we are modeling diurnal variations of illumination for South Pole region according to the variations of altitude of the sun above the horizon. Our calculations indicate that the permanently shaded areas near South Pole are lies not only in the inner part of polar craters, but at the smooth plains. According to data from KAGUYA (SELENE) these areas are characterized by rough topography and numerous small craters. These regions are coincide with larger number of small areas with high hydrogen content, discovered by Lunar Prospector and may contain deposits of volatile elements.
