You may have seen many desolate volcanic landscapes, but in the Jingbo Lake of Mudanjiang, there are different volcanic landscapes. Not only is it not desolate, but the vegetation is very rich and forms a spectacular crater virgin forest.
You may have seen many forests, but here, the "forest" grows underground. This crater virgin forest is special because it is an "underground forest", where you can see the crater geomorphology, a geological core area integrating volcanic landforms, biodiversity, forest health, and lakes and mountains.
The underground forest is far-reaching, mysterious and unique, attracting countless tourists.
The underground forest of the crater near Jingbo Lake, which was formed by a volcanic eruption about 10,000 years ago, formed a rare and rare "underground forest", so it is called the primeval forest of Huoshankou. These fire mountain passes are distributed from northeast to southwest, and there are 10 in the narrow strip of 40 kilometers long and 5 kilometers wide. Among them, the No. 3 Huoshankou is the largest, with a diameter of 550 meters and a depth of 200 meters.
There are a lot of steps and many steps here. It is really tiring, but the fresh air and strange plants are refreshing.
Passing a fire mountain pass, as soon as you get close to it, you can feel the cold air inside, which is 5 degrees colder than the place just 10 meters away. It is amazing.
Through this fire mountain pass, it is wonderful to see that there is a hole in the sky. We saw a deep crater, and it is hard to imagine what it was like 10,000 years ago.
Because it is deep in the mountains, the leaves on the mountain have changed color to become "Wuhua Mountain". Auntie is drying the mushroom under the mountain, saying that it was just taken from the deep mountains, it is delicious~
The crater forest is filled with cooled magma and barren trees.
Our group entered from the No. 4 crater and walked among them. The most obvious feeling was that "people are deep pits but they don't know." I saw the trees that were not complicated by the name. The main tree species include coniferous and broad-leaved mixed forests such as Korean pine, yellow pine, fish scale pine, stinking pine and larch. There are also broad-leaved tree species such as tall yellow radish, ash, walnut, sable, aspen, maple and Mongolian sorghum. The average tree height is about 20 meters, and the annual rings of many trees are around 400-500 years.
These deep pits in the crater forest are formed after the volcanic eruption stops, the magma cools and shrinks, and the bottom emptiness causes the inner wall of the crater to collapse. Over time, some of the rock and volcanic debris in the pit are weathered to form soil, and trees are gradually growing from the bottom of the volcano and the cliff crack. The forests in the crater are so lush, and they are rare at home and abroad. There is a cave at the bottom of the volcanic crater of
4. There is icy frozen soil at the end of the valley, and there is a clear spring at the end of the winter. The rock wall on the top is made up of many layers of volcanic eruptions. Sitting at the bottom of the hole, looking up, the blue sky and the mirror on the top of the head, the crystal clear, the blossoming white clouds drifting from time to time, the scenery in the view, hence the name "sit in the landscape."
Located in the Jingbo Lake Scenic Area, the Huoshankou National Forest Park has a history of more than 10,000 years and has thousands of rare and rare tree vegetation. The underground forest is derived from the eruption of the volcano. The original crater is now covered by lush forests. If the tourists stand on the top of the volcano and look down, only the green is refreshing. At the bottom, there are various pine forests, thousands of larch trees, and centuries-old spruce trees. Looking up at the sky, it is full of broad-leaved trees, and it is full of fun.
