Identifying direction using sand dunes is considered a relatively complex method in the desert.
If you're not an expert, it's best to use it with caution.
The method of using sand dunes to identify direction works very well in deserts primarily influenced by a single wind direction, such as trade winds.
People can find a certain pattern through the alignment of sand dunes, known as the sand ridge line.
Most of the time, the alignment of the sand dunes is perpendicular to the prevailing wind direction.
Therefore, once the direction of the trade winds is determined, it's easy to identify directions.
Dennis is an expert.
In the summer of the Great Sand Desert, influenced by the Indian Ocean, the northwestern region of Australia is dominated by northwesterly monsoons.
Therefore, the sand ridge lines are often aligned northeast-southwest.
By judging the sand ridge lines of the dunes and with the aid of the sun, Dennis was very accurate in determining directions before.
