Geological Corridor Introduction: The end of Wulong Gorge is a naturally occurring geological landscape area. On both sides of the place are steep cliffs formed by rock formations in earthquake fault zones, and at the foot are stone river channels formed by tens of thousands of years of water eroding riverbed rocks. There are purple-red sandstone and light gray granite in the river channel. The flowing water has carved into this natural stone trough into strange-shaped rocks such as "Mermaid" and "Rhinoceros Watching the Moon". Fossils of underwater aquatic organisms can be seen everywhere on the rocks. The geological corridor is about 50 meters long and 14 meters wide. It is a "geological museum" for appreciating geology, topography and landforms.
