Hexigten Global Geopark, Inner Mongolia, Northern China
Photo documentary from our road trip to Inner Mongolia. The second stop took us to a UNESCO geopark.

Initially we expected to change into electrical vehicles when entering the UNESCO geopark. Turned out the road block was unmanned and so we had to take our car into the geopark area. On the mountain ridge looking back down over the park.

When a large granite mass is exposed on the ground surface, the impact of thermal expansion and contraction or compression leads to the development of vertical fissures. In a cold environment, water ingresses fissures in the rock and expands when it turns into ice. This tremendous expansion force can cleave open hard rock.

The mountain ridge in Hexigten Geopark in completely covered with granite pillars that resemble a stone forest.

Facing the devastating power of ice and snow again and again as the seasons change, the rock is eventually shattered into blocks. The rock fissures expand progressively until the whole fomration becomes flat, broad space.

From afar, this densely layered rocks look like sedimentary rock, but a closer look reveals that it is actually granite. In the Ice Age, more than 100,000 years ago, this granite was covered by extensive glaciers, which caused compression from above. When the glaciers melted, this pressure was released, and the rock expanded slightly. The expansion process damaged the rock structure, leaving small horizontal fissures. Weathering completed the job and finally formations like this one, shaped like the wall of a fort appeared.

The Balancing Rock – a rhombic granite fomration cut out from two groups of vertical joints, measuring 3.2m long and 2.5m high. Weathering is more severe in the lower section and when rocks collapse under gravity a top-heavy shape appeared.

This colossal work of art is the result of natural processes over millions of years. In addition to the horizontal fissures, compression caused the development of another set of vertical fissures in the granite.
