At ADAK Is. in the Aleutian Chain there's a Crack in the Rocks, called Kagalaska Straight, used as a Shortcut to the 'other' end of the island.
I contacted a Chief with a boat to go around for some hunting.
He said we might not get through. The winds are pretty high today. Wow what an understatement that turned out to be.
When we got to the straight it looked like a Water fall turned up on it's side with Huge Choppy waves.
The surf was banging off one side, onto the other and rebounding.
Much taller than the boat and choppy in that the waves just existed in place. Not going in any particular direction.
I realized we might not be able to turn the boat around if we got into that stuff, and decided to forget it for that day.
I'm still here...
