Extended data:

Due to the large-scale volcanic eruption of Mesozoic Jurassic and Early Cretaceous in Yongtai County and the neotectonic movement since orogeny, the landform of Yongtai County has risen intermittently and formed a modern highland inclined from southwest to northeast. The county is dominated by middle and low mountains, and the elevation of most areas is 500 ~ 1000m, and the height difference is generally 300 ~ 500m, and some areas are around 1000m. The mountain is very high.

Due to the different weathering resistance of different volcanic rocks, the terrain is characterized by sharp peaks, strong cutting power and steep slopes. Only the intrusive rock area and some volcanic rock areas in Dazhangxi area are distributed in low mountains and hills and intermountain erosion basins. Roughly bounded by Dazhangxi, the terrain can be divided into southwest and northeast parts:

The mountains in the southwest are tall and majestic, with thousands of meters of peaks, fault planes, deep valleys and waterfalls. Among them, the nearly east-west main mountain range from Chishui in Songkou to Geling and Tang Qian runs through the south of Yongtai County, with a length of about100km and a width of about15km, and the elevation fluctuates from west to east. East Lake Peak is 168 1.9 meters above sea level, which is the highest peak in the county.

Its neighborhood is the highest and most magnificent in the county. Mountainous areas are often at an altitude of 1 100~ 1400 meters. The mountain ranges extending northward in Gaiyang and Changqing slowed down, and the altitude dropped from 1000 meters to about 800 meters. The mountains in the Chishi area in the east are slightly gentle, and the altitude is often around 600 meters. Further east to Linglu, the terrain is undulating, and thousands of meters of peaks are constantly reappearing. The height difference between the two sides of the stream changes greatly, and the terrain is steep, with many strange peaks, cliffs, strange rocks and cliffs, and some places look like karst. The terrain around Geling and Tang Qian slowed down again, and then disappeared in Fuzhou Plain.
