Hong Kong National Geopark was located at the East Dam of our High Island Reservoir. The English and Chinese names of the park are a little strange. I don’t know why it is called “National” since Hong Kong is not a country. I believe the person who named this Geopark would like to raise the reputation of Hong Kong to the world, telling people all around the world that Hong Kong owns a Geopark for its country.
The rocks here are volcanic. Their structures are mainly hexagonal prisms (六角柱體). They look strong and hard, but they break up along the cracks through weathering. From the broken parts, I discover that the cross-sections are not “perfect” regular hexagons as those we see in Mathematics.Some of these lava-built needle-like prisms did not come out vertically from the ground when they were first formed. They laid in a slanting manner. Some even appeared twisting when they had cooled down. Strange, isn’t it?

they were slanted or even twisted becos of the movement of the crust plates... Like the tall Himalayas was created by the compression between two plates and the rocks were squeezed upwards.
The first picture looks like a "face" with eyebrows, eyes and a mouth. The last right hand side picture is very interesting, we have never seen something like this before.
