Flag Fen Field Trip

Our class took a field trip to Flag Fen, where Professor Charly French had worked on the excavation of a Bronze Age wooden walkway, which connected an island in the fens to higher ground nearby. The timbers of the walkway were preserved for around 3,000 years because a rise in sea level has kept the timbers in a wet environment where bacteria (and other organisms which would decay the wood) could not grow in the absence of oxygen. A portion of the walkway is on display in a room without sunlight and treated with silver ions to prevent to the growth of bacteria.
