Introduction to the North Country Pillar: "The North Country Pillar" is a huge stone, T-shaped, about 10 meters high, like a huge mushroom, so it is also called the mushroom stone. A huge boulder (mushroom cap) on top of the stone pillar is crumbling, which is very dangerous. According to research, a volcano erupted in this area more than 100 million years ago. The hot acidic magma overflowing from the crater flowed on the ground within a radius of several kilometers. The erupted gravel and volcanic ash fell from time to time in the air, forming rhyolitic breccia tuff lava. The rocks around the "One Pillar of the North" were gradually eroded away because they were not as hard as it was. The only "One Pillar of the North" became an indomitable "hero". The stone pillar has four characters "North Country One Pillar" on it, which echoes "Southern Sky One Pillar". It is one of the iconic scenery of Huzhong Primeval Forest Resort and one of the most unique natural landscapes in the Greater Khingan Mountains.
