have been already published in a number of studies associated with analysis of
topography of the planets (Nikora and Goring

(see Fig.

) or Aharonson et al.
2001
); however, for the best of our knowledge, it is the first time that such figure is
presented in the relation to topography of exemplary polar region representing the
