Malström

Malström, or Maelström, a dangerous whirlpool off the coast of Norway, caused by the rushing of the currents of the ocean in a channel between two of the Loffoden Islands, and intensified at times by contrary winds, to the destruction often of particularly small craft caught in the eddies of it, and sometimes of whales attempting to pass through it.
