The location of Fong Chuei Sha is between Jialeshuei Scenic Area and LongPan Park, around the position on 48th kilometer of Jia-E highway. The landform of this area originally belongs to coral reef shore. However, the sand texture of Fong Chuei Sha is mixture of fine sand and red soil due to interaction of rain and wind power.Clear dry and wet season is the character of Hengchun Peninsula’s weather. In summer, southwest airflow is strong and brings adequate local rainfall. Rain water follows the landform streaming into sea and that becomes sand river scenery. Sand grains almost vertically stream into sea from the edge of tableland and that becomes sand waterfall scenery. In winter, strong northeast monsoon bring sand grains further from hill slope to hill top. These two reverse movements cause the special scenery of wind blowing sands.When wind blowing sand is at the most strong time, whatever you see is almost a desert. However, after Jia-E highway has been constructed and since there are plenty of beefwoods grown at costal for stopping wind and sands, this desert has been gradually covered by plants. The natural forces among wind, sand and rain are broken. The scenery in Fong Chuei Sha is not as it was.Leaving Fong Chuei Sha for Jialeshuei Scenic Area, first you will see the welcoming stela made by Manjhou Township Office. There are some sand dunes near the welcoming stela, and they are ancient sand dunes. An ancient sand dune is hard limestone formed by some old sand dunes due to cementation. These limestone is also knows as bioclastic limestone for including some coral fragments and shells. Observing the profile of limestone in detail, we can obviously see layers of stone slices parallelly aligned. It’s large-scale cross-stratification formed by wind. Only sand dunes accumulated on land will form cross-stratification in large oblique angle and that is a very rare.
