Contest #432 Hint

Is that a river or a lake? In the winter of 1996-97, something happened to change the look of this location in a big way.

How to Play

To participate, just make your guess in the comments section for each photo. Guesses will be held until the end of the contest, when they will all be made public. Anything and everything is fair game for getting a correct answer. Each contest will last one week, starting on Friday. Each Wednesday at 0:00 hrs GMT a hint will be published. If you submit a correct answer before the hint is out, you'll earn an extra point, so submit your guess as soon as you have an idea.
