The south-western side of South Georgia is largely snow-covered and has an abundance of glaciers. These scour their way, imperceptibly, down to the shore where, upon meeting the warmer ocean water, they calve chunks of ice into the sea. In calm conditions the resulting brash ice will fan out across the surface of the sea for a mile or more. As the yacht Golden Fleece pushed her way through this soup of crushed ice and 'bergy bits', a party of cape petrels flew past, low over the water. I loved the way that reflected light from the greygreen brash ice filled the shadows under the birds and their white undersides became almost lost against the background.
