The infinite shapes and textures of icebergs in Antarctica fascinate me again and again. Every iceberg is unique in its formation, size, and shape. Some are small, while others are massive, towering behemoths that dwarf everything around them. But what really captures the imagination is the intricate network of ridges and channels that make up their surfaces. Some of the most stunning shapes and textures are created by the melting of the iceberg's surface. As the sun beats down on the ice, it causes it to melt and refreeze, creating intricate patterns of ridges that seem to go on forever.
