    How do I tell the difference between a boulder and a blotch?

    Boulders tend to be bright features and fairly small. if your eyes haven't got used to the site yet they may look like small pits in the surface : APF0000x7s (up and left of center)

    A Blotch is typically much larger and will be very dark/black and will look much like this APF00001kl

    difference between a fan and a blotch is mainly shape, a blotch will be roundish and a fan will be wind blown, elongated and fairly obviously formed from a source at one end. APF0000x3f
