Steel wall won't rust

How does that steel keep from corroding? What if it would rust away? Those questions might be the first things to pop up when one considers the fact that deep in the bowels of Fort Peck Dam stands a cutoff wall made from 34 million pounds of steel sheeting. It relieves most people to hear the answer: since the steel was pounded, jammed and crammed deep into that floor of bentonite and shale below, and since it was heaped on by impervious clay, and since air is hard to find down there, little if any rusting takes place. What does take place is the subsequent prevention of underseepage and its potentially disastrous effects. That adds up, of course, to a safe, secure feeling for those downstream of the dam. In this photo, note the location of the townsite (centered and to the right) and the dredge cuts (left foreground).
