Unusual terrain?

I'm curious as to the type of terrain this could be and what the blotches are, could they be the starts of fans?

no, blotches and fans are basically the same thing except that the dust from fans is spread by the wind in a distinctive way - being a conical (sometimes near linear) dispersion with the greatest density of dust deposition near the source and following the wind direction
when you can't tell where the source is and where the direction of dispersion lies it's a blotch, when you can it's a fan
