Giant Porch Pillar

Sao Cheliang Yai is a sandstone layer formed by the accumulation of water sediments in the past. It is approximately 100 million years old or in the Mesozoic era. It is classified in the Phu Phan rock group, Khorat rock group. The current geomorphology is the result of the sandstone layer changing its structure due to the expansion and contraction of the hot weather during the day and the cold weather at night, causing the rock layer to have cracks and fractures. Later, there was erosion from water currents and wind. The eroded part was destroyed and blown away. The remaining part gave the shape of "Sao Cheliang Yai". #tripแจกโรงแรมฟรี
