Limestone arch


The Oparara river system has been sculpting the 35-million-year-old limestone into an intriguing complex of caves, arches and channels for millions of years. This arch is known as Moria Gate. I was intrigued with textures in the limestone and how they contrasted with the smooth tea-coloured water. The ‘window’ of native bush gives the viewer a glimpse of what’s on the other side.
