Just south of Jinguashi on Provincial Hwy 2 (KM81.5) is a quirky bit of eroded coastline. The most famous formation is a swirling tower that genuinely looks like a striped ice-cream cone.
The odd shapes and colours were formed by the sea and wind eroding sandstone rocks that just happened to have rich iron and copper deposits in them. As the metals were exposed to the air they oxidised leaving the outside of the stones striped with colourful bands.
