When the winds kick up the heavy stuff would either not move or only move to lower points.

The lighter stuff capable of being lifted by the winds would carry higher into the atmosphere and thus only the lightest would be deposited on the highest points.

The top reaches of Mons Olympus should have a good covering of very very fine material.
