David H. Levy's Evening Stars: The big brown nothing
September 2009: When Earth's most extreme tides are low, the water level drops 50 feet. This leaves a lot of brown mud.

What is that thing out there?" my wife Wendee asked anxiously while she looked out the north-facing window of our guest room in Nova Scotia. Our host and friend, physics professor Roy Bishop, needed details. "What thing? Is it an animal?"
The vertical water level in Minas Basin of the Bay of Fundy changes dramatically depending on low or high tide. Here the basin is at high tide, and ice flows in the cold water.
