A dense series of human and animal footprints came to light in lot 1, as in other lots on the route of the TAV railway, above the primary deposit of the so-called Pomici di Avellino eruption (3457 + 66 b.p. 18th century B.C.).

The footprints, which attest an intense passage of individuals and animals sometime soon after the formation of the deposit itself, are impressed in the various layers of mud which were deposited in the decades following the Pomici di Avellino eruption. Amongst the animal prints those of cattle, dogs, sheep/goat and horses were recognisable, often associated over vast, extraordinarily crowded surface areas. A three dimensional survey was made of the most important footprints with the aim of recovering completely new anthropological and faunal data, through the laser scanning of the ground surface.
