Cave del Valle, Cantabria

Cave del Valle (Spanish: Cueva del Valle, The Valley's Cave), locally also known as La Viejarrona (Old Girl), is located near El Cerro Village in the municipality of Rasines in Cantabria, northern Spain [1]. The cave is the source of the Silencio River, a tributary of the Rio Ruahermosa, which in turn is a tributary of the Asón River [1]. Documented are Azilian harpoons and scrapers, Upper Magdalenian spear points and other bone tools [1]. Stone tools include chisels and various types of scrapers [1]. A perforated and decorated stick of archaeological interest was found at this site, but is now lost [1]. The cave of the valley is recognized as one of the longest explored caves in the world with more than 40 mi yet explored [1].
