This is another worthy sight to see, Cullernose Point, the rugged rocks jetting out into the North Sea. I could see the white bits on the rocks and thought it must be seagull crapping, but when I got closer there were no seagulls there

The rocks on the North side of the haven reveal distinct layers of pale and black rock, formed in calm estuarine conditions. The black rock, made of shale or mudstone, settled in slow-moving water, while the paler rock, composed of fine-grained sandstone or siltstone, formed in slightly faster currents. Keep an eye out for remnants of a marine sandbank and a thin coal seam, offering glimpses into the area's past. As you continue, notice the tabular crossbedding in the sandstone, resembling patterns formed by flowing water around obstacles. These layers showcase the dynamic forces that have shaped this remarkable landscape. On the South side, a similar sequence can be observed, sans the coal. The sandstones, with their warm yellow to brown colors, owe their hues to ferric hydroxide, adding a touch of vibrancy to the scenery. Pay attention to the subtle differences in the rock layers' orientation. The varying strikes—around 50 degrees on the North side and 30 degrees on the South side—hint at a fault's presence, influencing the land and guiding the path of the Howick burn.
