I heard there was to be a looking for of volcanic activity here on the home globe to compare to mars (boulder formation), thought these liquid analogs might float!

in response to Mote's comment.
Hi Mote,
it's an interesting idea. The origin of the boulders is not completely solved.
Mars isn't volcanic active on Mars anymore. There's much geologic evidence from orbit that it was volcanicly active much earlier on its history. The boulders are really only found in the Inca City region. It's the region we're currently focusing on. The thought it that the boulders might be formed after an impact. I think that jives better to constrict their location on the South Pole.
Also interesting we know it's core is pretty much dead compared to the Earth's, that's where there is no magnetic field on Mars like on Earth. That requires a metallic liquid outer core, so the thought is it's outer core has cooled off enough on Mars to be solid
Cheers,
~Meg

great image. I note Ushkovsky seems to have lost it's top! Also see pimples/lumps such as we see commented on in some images of Inca city in the terraine in the upper right of the view. ~Pete
Whoops, I forgot to comment on -"limpets". Yes indeed Wassock, and don't those nice sharp triangular shadows look very familiar!
Time for you Angi to start a chat on your thread! 😃Posted
