Scenic Introduction
Affected by the Yanshanian and Caledonian orogenic movements, strata spanning more than a dozen geological ages from ancient times to the present are distributed and exposed across Wuhai, forming a host of unique natural landscapes, such as mushroom rocks, stone flower caves, flying peaks and One-Line Sky.
Stretching over 250 meters in total length, One-Line Sky is flanked by towering vertical cliffs that look as if they were hewn by axes and blades. Its narrowest point is merely one meter wide. Looking upward, the sky appears like a flowing blue silk ribbon floating overhead.
