Raining sands.

    It looks like a star trails image embedded into the ground. It doesn't match the direction of black mark on the left side of the image, so it really makes me curious as to what would cause this?

    There are lots of areas like this, it has been suggested that the lines are glacial features caused by rocks under a moving ice sheet. But they look like grooves which probably means they are raise features.
    The fan is coming out of a straight line feature at right angles to the lines, seen this elsewhere with fissures cutting right across the line features.

    Thanks. I did lines do look like a glacier event of some kind. I think it amazing to consider the event that took place.
