This small tuffière owes its name to the porous stone known as tuff. Tuff comes from a deposit of limestone dissolved during the crossing of the Langres plateau. In contact with the air and vegetation, the limestone is deposited on the mosses, eventually creating successive small dams, giving rise to this small natural staircase. Because of its small size and the immediate proximity of the road, this site, which is not fenced off, remains a fragile natural environment: take care not to step on it, so that one day it may become as big as the tuffière at Amorey or Rolampont.
