Lake Superior is enormous. Its deepest point is 733 feet below sea level, which qualifies it as the lowest--and most insulated--point in the continental interior of the United States. The water at the bottom of the lake is so well insulated, in fact, that it stays a constant 39°F and only mixes with the warmer water above it twice each year (when the whole lake is 39 degrees).
