@ Alec Salt and Sherry: sorry for the confusion. I’ve reworded the caption for that image to make it clear that the “shadow” is really an area where the wind has swept away the light-colored dust.

I was thrown by that too, wind doesn’t cause shadows, I think they worded that slightly wrong.

Don’t be so literal. It’s an apparent shadow. Do you really need ‘shadow’ to be put into quotes?

On the last picture, I’ve never heard of “a shadow created by Martian winds”. Shadows are usually created by something obstructing light. So is it a shadow or is it not a shadow? Do the laws of physics work differently on Mars? i.e. do winds cause shadows, not light.

I like the scaley sand dunes. Looks like fish-shaped Long Island

Clearly visible on the last photo.

Somebody has written, “NASA/JPL/ASU” on the surface of Mars.

Oh when will the vandalism end?
