A fantastic variety of shapes result from both the formation and deterioration processes of icebergs. Like snowflakes, no two icebergs are exactly the same, but there are certain basic categories of shapes that are used for iceberg observations. TABULAR: Steep sides with a flat top - like a huge tablet.

PINNACLE: An iceberg with one or more spires. The term NON-TABULAR is sometimes used to cover all icebergs that are not tabular-shaped (No.1). This includes bergs that are dome-shaped, wedge-shaped, blocky, and pinnacled. In addition to shape, icebergs are also classified as to size.

An iceberg or ice mountain is a large piece of freshwater ice that has broken off a glacier or an ice shelf and is floating freely in open water. It may subsequently become frozen into pack ice (one form of sea ice).
