There is a crater gently inclined to the south at the top of the mountain, which contains water, forming a strange landscape of swamp crater, which is characterized by a round back crater and a flat crater that accumulates water to form a swamp wetland. The cone consists of black and red pumice and almond-shaped basalt. The south and north Graciu Mountains are high in the south and low in the north, and small in the south and small in the north, which constitute the obvious topography of Shuang Shan. There are 2 meters of oak trees growing in the highland on the east side of Mount Graqiu, which has become a north-south banded forest and is flourishing.
There are mysterious ancient caves on the mountainside of North Graciu Mountain. Some people say it's the headquarters of the Japanese army in World War II, while others say it's the cave of the giant snake.
South Graciu Mountain, known as "Fuqing Mountain" in ancient times, is located in the north of West Volcano. The mountain is composed of aggregate rocks, and the outer slope has obvious blue-green uplift, which is called "denuded sheep tail ditch" strip in geology. There are ancient trees and green cages, and birds and animals are in groups. South Graciu Mountain is the highest and most typical cone among the fourteen volcanoes. The mountain is complete, and the top crater is round and basin-shaped. It used to have a mysterious lake water of more than two million years, and it is a pearl of Wudalianchi Volcano Group.
Among the Wudalianchi Volcanoes, the earliest eruption is the South Graqiu Mountain, which has been more than two million years. People call South Graqiu Mountain Father and Son Mountain, leaving a beautiful Tianchi scenic spot.
Here, we can not only appreciate the wonderful beauty of ancient volcanic scenery from the horizontal direction, but also appreciate the vicissitudes of the earth from the vertical direction.
The most famous are the panoramic photos of Tianchi Mountain taken by Guo, a researcher at the National Academy of Geology, and the iconic photos promoted by Wudalianchi, which constantly appear in various pictorial and propaganda media. From the photo, you can clearly see the claw-like ditch flowing out of the volcano, radiating from the pool to the foot of the mountain. Vegetation composed of dark green trees and shrubs and grass blankets composed of Artemisia annua are scattered all over the mountain, giving people a yearning feeling.
Tianchi is 500 meters in diameter and is called "Tianchi Bonsai" because of its exquisiteness. Tianchi Lake was endowed with a pool of holy water. The sacred lake hangs high and the scenery falls from the sky. In summer, the leaves on the lake caress the water surface, and wild ducks play in the lake, which is as clear as jade and has a variety of customs.
