Description
Morphology
This is a cavity formed along a joint with the floor filled in; it ends in a fissure at the bottom that is currently not passable. Descending trend.
Progression
Easy traversability, with the recommended period being all year. Progression difficulty: climbs and narrow squeezes. Temporary rigging: a thirty-meter rope to be anchored to a tree at the entrance.
Other details
Geology: Montenero is a Mesozoic carbonate block; its "island" shape is due to its emergence in the Pleistocene sea, confirmed by the presence of borings made by lithophagous organisms at an elevation of 300 m above sea level. From: E. Squazzini in the Proceedings of the 2005 Amelia Conference.
History
Paleoethnological finds. Archaeology and paleoethnology: of interest due to the presence of bones, it was the subject of excavation campaigns by the Soprintendenza around 1998-99 and most recently in 2004-2005. In November 2005, at the conference held in Amelia "Uomini, terre e materiali: aspetti dell'antica Ameria tra paleontologia e tardoantico", a paper was presented by M.C. De Angelis-R. Sardella-E. Squazzini-G. Manzi entitled "Il sito di Montenero di Amelia, fauna e resti antropici". Protection of historical-archaeological sites: yes. Studies: paleoethnological. Cadastral chronology: it has never been registered even though its discovery dates back to the '90s. Notes on the name: so called by its discoverer Stefano Baroncini but also referred to in some scientific publications as Grotta delle Ossa.
