Or catch of whiff of the local air and ask, "OK, Who dealt it?"

Methane is odorless.

There is Carbon dioxide ice on Mars, but the team that photographed this said it is water ice.

The Martian Methane Surprise
Interview with Mike Mumma
Astrobiology Magazine
There was a major dust storm in December of 2003, and it raised the scattering level from the surface to a higher altitude - probably about 20 kilometers above the surface - and this reduced the signature of both water and methane spectral lines of reflected light. Those conditions continued until June of this year. That means that when Mars Express tried to measure methane, they were looking against that background of dust and airborne ice. That would've affected their measurements and made derived abundances appear smaller than they would otherwise be... But in March 2003, the martian atmosphere was fairly clear. We were able to measure both water vapor and methane in the same spectra at the same time. We compared the water at each position with the amount detected by the TES spectrometer on the orbiting Mars Global Surveyor... Our water abundances were a factor of three smaller than those of TES. We always have to add a reference level to our spectral measurements to get the true value. I didn't add those numbers in my presentation this year [at the DPS conference]. Instead, I showed the minimum amount we were seeing.
