A replica of the Sweet Track

• The Post Track, an ancient causeway in the Somerset Levels, England, is built, ca. 3838 BC. It is one of the oldest engineered roads discovered in Northern Europe.
• The Sweet Track, an ancient causeway also in the Somerset Levels, the oldest timber trackway discovered in Northern Europe, is built in 3807 BC or 3806 BC, tree-ring dating (Dendrochronology) enabled very precise dating.^[1]
• Plough in use.
• 5.9 kiloyear event, one of the most intense aridification events during the Holocene. It ended the Neolithic Subpluvial and likely initiated the most recent desiccation of the Sahara desert, triggering migration to river valleys, such as from central North Africa to the Nile valley.
