The kids can’t have all the fun, which is why we’ve created a challenging puzzle for parents.
As the old saying goes, “Beauty is in the eye of the beholder”. Looking at this abstract image, what do you see and feel? Does it spark a sense of wonder, do you find it eerie? Is it a topographical map of a snow-blasted mountainscape? No! It’s a concrete wall within the underground tunnels of North Fort at North Head Sanctuary.
The colours and textures are the result of efflorescence, which is a process of water seeping through masonry to produce salt deposits and discoloration. In this case, efflorescence is the result of natural water coursing through the 200-metre-long tunnel complex. Think you have what it takes to solve this puzzle?
