Icebergs at Cape Perez, Antarctic Peninsula. A small boat is dwarfed by several bergs clustered around Cape Perez on the Peninsula. Bergs can have an infinite variety of size and form. There are many bergy bits (floating ice less than 5m above sea level, and not more than 10m across) and brash ice (ice fragments not larger than 2m across) in the foreground, with land ice below the rock cliffs, ending in coastal ice cliffs. In the distance, high mountains of the Antarctic Peninsula are obscured by mist.
