For me, the most compelling evidence for recent water on mars are the pictures of flows on crater walls.
What if, like on Earth, water is contained in aquifers. It may not be evenly distributed. Granted this water is frozen.
Is it possible that a meteor strike might "un-earth" the ice and raise the tempeture long enough to melt the ice and create the flows like the ones seen in the picture?
