Stilting

Stilting is a tech from the Neolithic Era. Prehistoric bridge-building began with simple stepping stones or felling trees across gullies. The increasing use of sledge transport necessitates more durable means of traversing water. With the discovery of stilting techniques, ancient man learns to drive piles into the riverbed to span aquatic distances with greater efficiency.
