Which is Earth?

We had another great day at Great Sand Dunes National Park and Preserve today, with lots of pictures, but it also involved a lot of hiking and I’m tired. So instead of a full post, I will refer you to my adviser’s post about our first day at the dunes, over at the Planetary Society blog. I’m also stealing the image that he posted over there, comparing granule ripples on mars to the ones that we saw at the dunes. Can you tell which one is Earth and which is Mars? Check Jim’s post to find out.
