Summary

DescriptionPickering crater p54.jpg	English: Pickering crater, on Mars. This is a figure on p.54 of NASA SP-441: VIKING ORBITER VIEWS OF MARS, which has the following caption: Extensive Lava Flows from Arsia Mons. The flows that erupted from Arsia Mons extend some 1500 km away from the summit and bury the older cratered terrain of the southern hemisphere. Flow fronts are visible within the large crater Pickering (120-km-diameter) where they have been diverted around high ground associated with the central peak of the crater. Flows of this type associated with the big volcanoes may have lengths in excess of 1000 km and may resemble the large flows found in Mare Imbrium on the Moon. The discovery of these flows on the outer flanks of the major volcanoes on Mars has shown that the basal diameter of many of these volcanoes is considerably larger than was suspected from Mariner 9 data. 56A12; 34°S 133°W
