Was looking at some MGS imagery:



Kind of a low-contrast scene with some darker splotches here and there. Running that through an equalizing filter gives this image:



Some surprising detail brought out there--it looks to me like there are small clouds casting shadows on the surface. Can that be right? They could be little hills I suppose.

I wouldn't be at all surprised to see clouds around the Phoenix site. In fact, I'm pretty certain Phoenix herself captured some images of clouds from the ground. Here's a highly downsampled image from Sol 5:

This is just one of several sky images from that sol. They all show patterning in the sky that seems to suggest clouds, to me.

Besides, we're in the Land of the Polar Hood Clouds. This latitude on Mars has been observed from Earth as developing cloud decks which regularly obscure the scene from telescopic observers.

Interesting... makes sense, as the subliming H2O has to go somewhere!
