Passage: The track was discovered in 1970 during peat excavations and is named after its finder, Ray Sweet. The company for which he worked, E. J. Godwin, sent part of a plank from the track to John Coles, an assistant lecturer in archaeology at Cambridge University, who had carried out some excavations on nearby trackways. Coles' interest in the trackways led to the Somerset Levels Project, which ran from 1973 to 1989, funded by various donors including English Heritage. The project undertook a range of local archaeological activities, and established the economic and geographic significance of various trackways from the third and first millennia BC. The work of John Coles, Bryony Coles, and the Somerset Levels Project was recognised in 1996 when they won the Imperial Chemical Industries (ICI) Award for the best archaeological project offering a major contribution to knowledge, and in 2006 with the European Archaeological Heritage Prize.Dendrochronology (tree-ring dating) of the timbers has enabled precise dating of the track, showing it was built in 3807 BC. This dating led to claims that the Sweet Track was the oldest roadway in the world, until the discovery in 2009 of a 6,000-year-old trackway built in 4100 BC, in Plumstead, near Belmarsh prison. Analysis of the Sweet Track's timbers has aided research into Neolithic Era dendrochronology; comparisons with wood from the River Trent and a submerged forest at Stolford enabled a fuller mapping of the rings, and their relationship with the climate of the period.The wood used to build the track is now classed as bog-wood, the name given to wood (of any source) that for long periods (sometimes hundreds of thousands of years) has been buried in peat bogs, and kept from decaying by the acidic and anaerobic bog conditions. Bog-wood usually is stained brown by tannins dissolved in the acidic water, and represents an early stage of fossilisation. The age of the track prompted large-scale excavations in 1973, funded by the Department of the Environment.
