Geoff pointing out the (apparently not so) obvious flaw in the Campbell Scientific snow-depth sensor.
Melting snow on the sensor drips onto the snow it's supposed to be measuring the depth of. D'oh! Or is that Sn'oh!

Note Geoff is holding his patented snow-depth measuring doofah for comparison - still think it should've been any colour other than white ;-)

Had to go out in a blizzard to get this shot - intrepid or wot?!
