Snow What?

This looks familiar, right?  Someone drew a snowman in the snow and took a black and white picture. Nope.  It is an impact crater on Mars!  But are they sure?  Remember the whole Face-on-Mars thing?  This could totally be a message from a highly advanced race of snowpeople.  Or it could be what the caption describes: "Scientists ... have discovered a crater that appears to have formed on Mars in the past 20 or so Earth years, and have used it and several other similar craters to estimate the present cratering rate on Mars." I'm all for figuring out the cratering rate. I mean, we have to know!  But the alien snowman theory is way cooler.
