flaw lead
FLAW leed
A predictable corridor of open water separating shorefast ice from the moving pack — a seam in the ice that follows the coastline and stays open through pressure and current. For hunters and polar bears, the flaw lead is where life concentrates.
Etymology
English: flaw (a gust of wind, from Old Norse flaga, a slab) + lead (open water passage). The flaw is the wind that keeps the lead open.
