But I did not see on pages 32-34 anything about sinking into water, as implied by your fortune cookie. One set of pilings was reported to have tilted 7 degrees. So, either one piling sunk or the other rose. I mention the possibility of rising because thawing could introduce the action of frost heave.

I propose the following fortune cookie:

What will thawing permafrost do to the integrity of the Alaska Pipeline, and to any other structures built on the assumption of permafrost forever?
