These are structures that generate in frozen oceans and their deep variants. They consist primarily of packed ice with a little bit of ice and blue ice, and can be topped with snow. They are the only place where blue ice can be found naturally besides snowy taiga villages. Icebergs generate in a wide variety of shapes and sizes, ranging from small "islands" to giant mountain-like ice structures. They can also generate with "cave-like" holes in them, which sometimes reach to the other side of the iceberg. There is a rare chance of a icecap to generate with only blue ice and snow.
