Hi Odysseus I would think like the Earth Mars south pole would be the
coldest. Could at the Mars poles be any CO2 snow flakes? Maybe a sand
storm kicking up some of that frost. Seems the extreme temperature drop
from day to night on Mars might be a greater extreme than the hottest
summer day at the Earth's equator as to its coldest day in winter at the
south pole. Mars must have a permanent frost just 6 inches under its
surface at its equator That could be the reason large rocks sit so high
up on its sandy surface. Bert.
