GeoPark

Went to the GeoPark again today (Wednesday).  Specifically, we went to the East Dam of Highland Reservoir, to look

at the prismatic columns around the dam.  

100 million years ago, all of Sai Kung was a huge active volcano.  

In time, molten lava cooled and solidified into hard rocks.  

In the process, they contracted and fractured into hexagonal columns.  

Earthquakes and other movements tilted, bent and sheared the columns into fantastic shapes. 

A quarry was set up to provide the stones for the building of the dam to create the reservoir.  In the process some of the rock formations came to light, while others are buried by the dam itself. 

Enough remains for us to admire.
