The 22nd day of the northeast tour of the Tianchi of Aershan (1～3) in the rain to visit Shitang Forest Yao want to visit the northeast on the 21st day of the northeast tour of Aershan Luofengling Tianchi, Grand Canyon, Dujuan Lake, Triasse Gorge.

Shitang Forest, located in the skyscraper of Aershan, Hinggan League, Inner Mongolia, is the highest volcanic cone in Da Hinggan Mountain. The magma from the volcano forms a broad lava mat and lava quilt on the ground, and lava above the ground often forms a platform. The most spectacular is the lava pond along the Great Black Grove. Within 200 square kilometers, in a sea of rough lava, there are magical landscapes such as overturned rock, lava fins, lava ropes, lava dishes, lava caves, jet cones, lava valleys, underground dark rivers and other areas.

The Shitang Forest was formed in the Holocene 10,000 years ago. It formed when the lava from the volcano flowed to the Harraha River condensed, and the lava flow that continued to flow forward at the back crushed and pushed the solid or semi-plastic rock that was condensed. The rock fragments were forced to move forward and were constantly blocked, and eventually black and brown basalt exposed to the surface to form various volcanic lava landscapes. This strange rock-rock platform is commonly known as the Shitang Forest. It is the largest recent dead volcanic basalt landform in Asia, geological structure, soil, vegetation, biota, all maintained primitive state, biological diversity, reproduced the whole process of the succession of low-level plants to higher plants.

A volcanic lava landscape in Aershan National Forest Park

Aershan Shitang Forest is a geological relics of Quaternary volcanic eruption. It is the largest recent dead volcanic basalt geomorphology in Asia. Geological structure, soil, vegetation, and biota are all kept in primitive state and biological diversity. The whole process of succession of low-level plants to higher plants is reproduced. High scientific research and conservation value. It is worth visiting here when you go to Aershan.

Entering Shitang Forest, like entering the natural and complete volcanic rock geological museum, here are the geological relics formed by multiple volcanic eruptions in history, the magma of the volcanic eruption covers the ground to form a broad lava mat, lava quilt, etc., lava above the ground often form platforms. The vast lava platform in Aershan, which covers an area of 1,000 square kilometers, of which the most spectacular is the formation of the Daheigou area of 20 kilometers long, Shitang Forest Shitang Forest 10 kilometers wide Shitang landform, known as "Daheigou basalt", lithological alkaline basalt and olive basalt. The rock pond is like a rough lava ocean, forming a variety of lava forms, including flip floral stones, lava fins, lava ropes, lava dishes, lava caves, lava hills, jet cones, lava valleys, underground dark rivers and other magical landscapes. Melt is also found in large areas of volcanic lava landforms The rock turtle back structure, according to geologists, is the only large-scale, well-developed and well-preserved lava back structure in China. In addition, there are hundreds of lava hills, which is the only basalt geomorphology that can be seen here in the country at present. This lava hill is mostly in the shape of a hoe, with a diameter of 5-7 meters and a height of 2-4 meters. There is a venting hole in the middle, which makes the top and side of the lava hill often crack, forming a cracked hole. Deep-source inclusions - Erhui olive and olive, garnet, etc. are also found in basalt. These are of great scientific value to the tectonic environment in the deep crust. In the stone pond where there is no accumulation of soil, there are tall and upright larchs, large swaths of cypress, pine, Venus plum, Yinxing plum and other plants. In the stone pond forest, the strange stones of the earth are dependent on the trees and the flowers and plants are blended. Clear stone stream, quiet water pools are now and then, jumping stone rabbits sometimes make a crisp sound, forming a wonderful spectacular, lively and clever stone forest painting.

Very good, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah
