The grey shaded area is the normal range of iceberg distribution. The extreme icebergs/growlers are indicated. Some of the notable extreme icebergs are:

  • In 1926, the southernmost known iceberg (a growler) reached 30-20 N, 62-32 W (about 150 nm from Bermuda).
  • In 1883, a growler was located about 200 nm south of the Azores.
  • In 1907, an iceberg was sighted about 100 nm southwest of Fastnet, Ireland.
  • In 1912, a growler was seen about 75 nm east of Chesapeake Bay, USA.
  • In 1912, the iceberg that the R.M.S. Titanic collided with was located at 41-46N, 50-12W.

This is a black and white chart of the locations of icebergs reported outside the normal range of distribution.
