Introduction to Tianmo Peak: Adjacent to Tianmo Lake, it is a steep rock peak pillar that rises upright. The peak pillar is formed by spherical weathering along two sets of structural joints. Its top is formed by spherical weathering along the original layer joints to form a three-section boulder. It resembles the bottom of the mill, the disc and the upper mill. Because it is on the top of the mountain, it is named Tianmo Peak.
