The shores and waters of Lake Superior can change dramatically from day to day. After two days of calm, the lake revolted with waves of ice crashing against the rocky shoreline. I have never heard such a sound and eagerly made a recording. These waves were literally made up of water and densely packed plates of ice. When each wave would crest, shards of ice clattered down the trough of the wave, and when they reached the shore the plates of ice would shatter against the rocks.
