Iceberg (feature)

An iceberg is a feature composed of blue ice or packed ice. There is also a terrain feature known as an iceberg, see Terrain features.

Generation
Iceberg feature generates in frozen oceans and deep frozen oceans. They consist of packed ice or sometimes blue ice, and there's a probability of 30% that an iceberg feature is topped with snow blocks.

Unlike iceberg terrain feature, iceberg feature is usually small. Iceberg terrain features generate in a wide variety of shapes and sizes, ranging from small islands to giant mountain-like icebergs.

Iceberg features have two types: circle-shaped and ellipse-shaped. There's a probability of 30% that an iceberg feature is ellipse shaped. For a circle-shaped icebergs, its radius is from 0 to 11; its height above sea level has a 90% chance of being from 3 to 17 and 10% chance of being from 10 to 42; its depth below sea level is from 3 to 18; it has a 30% chance of being carved. For an ellipse-shaped iceberg, the length of its major axis is from 7 to 11; the length of its minor axis is from 3 to 5; its height above sea level is from 6 to 11; its depth below sea level is from 6 to 18; it has a 90% chance of being carved.

Blue ice feature
Packed ice iceberg generates sometimes with blue ice features attached to it. A blue ice feature is a pile of blue ices, which generates adjacent to a packed ice and at or below the surface of water.
