Located at an altitude of 3,650 meters, Mount Syue No. 1 cirque is the most representative "cirque terrain" in Taiwan. It is also a rare glacial relic located in the subtropical region, leaving the most direct evidence for the existence of glaciers in Taiwan's high mountains. In the early morning of August 23, under the rising sun, the entire cirque was attractive red, and the shadows of people who were excited to take pictures can be seen below the photo. Mount Syue No. 1 cirque is also one of the top ten landforms in Taiwan.
