We calculated the temperature regime of an active region considered as a conical hole in dust layer. All the calculations are carried out for the case when the season effects are distinctly expressed. The temperature is defined from the geometrical parameters of the active region separately for ice bottom and dust walls. It is shown that dust walls are cooled very slowly for the small vertex angles of the crater structure. The temperature of the ice bottom practically does not change over the whole period of rotation, because it is retained at an approximately constant level by concentration of reradiated energy from the dust walls heated by the Sun.
