Description

These geologic maps of the north and south polar regions of Mars, extend to 55 degrees north and south latitude. The maps were compiled from Viking medium-resolution photomosaics at scales of 1:2,000,000. The north and south polar regions are strikingly different in physiography, geology, relative age, and surface processes. Most of the differences reflect the contrast between younger lowland plains of the northern hemisphere and older highland terrains of the southern. ENVELOPE STATES REPRINTED IN 1998
