My first thought was that not long ago scientists were jumping up and down getting all exited because they found salt. Now there is tto much? Also, in
order for there to have been life there must have been liquid water. We have no idea if it did let alone how much there might have been.
Just my thoughts....


I would say yes of the Mars we see today but oceans affect weather and who knows what it was like back when mars had large amounts of
surface water but being too salty kind makes since like Salt Lake, or the Dead Sea where slowly the ocean water is evaporated away and you end up with
things like the Salt Flat etc.
