Some icebergs I saw in Antarctica were enormous. This one was 20-30 metres high at least. I saw some that were even bigger! I saw this one from a boat, but the boatman wasn't allowed to go through the arch in case the berg collapsed! Have a look at this site to find out where big icebergs currently are. And go here for an iceberg database. And have a look at this site to find out how icebergs are tracked. I read somewhere that the biggest iceberg ever was larger than Belgium!
