Abisso di Malga Fossetta

Last updated December 21, 2021

Abisso di Malga Fossetta (The Abyss of Malga Fossetta) is a deep cavity of the plateau of the Sette Comuni, a complex of karst full of caves (2,562 explored in 2009). The abyss is located in the municipality of Enego, in the province of Vicenza. The abyss of Malga Fossetta, with its currently known depth of more than 1,000 m, is the second deepest cavity in Veneto (the first to be discovered to exceed 1000 m deep) and one of the deepest in Italy.^[1]^[2]^[3]

Location

The entrance of the abyss lies in the immediate vicinity of Malga Fossetta (named after it), precisely at 1744m above sea level in the so-called Bosco dei Larese, not far from the slopes of Mount Ortigara, on the plateau of Asiago. At the entrance there is a large green metallic cylinder that forms the winter entrance of the cave, because in winter the snow covers the ground for several meters.

History

The cavity was discovered by the Grotte Schio Group (GGS) in the seventies of the last century and its exploration lasted for almost two decades before a momentary stop. It was the Growth Group "E. Roner" in Rovereto that, starting from the mid-nineties, went back to exploring the cave. Subsequently, the two groups joined forces and on June 3, 2011, together with the CAI Grotto Group, the caves had reached the new depth of 1,011 m (previously the cave had been measured deep-974 m).^[5]

Geomorphology

The cavity appears as a long sequence of wells varying depths. The wells are generally wide and, at least up to -400 m, the maximum vertical is 54 m. In addition to -450m there is an enormous cascade well of 200m depth where, after passing a long and small meander and a subsequent series of small wells, the cave doubled to reach the old -940m bottom and the current bottom - 1011m. The cave develops initially in the Calcari Grigi and then almost completely in the Dolomia Principale.^[6]

A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word cave can also refer to much smaller openings such as sea caves, rock shelters, and grottos, though strictly speaking a cave is exogene, meaning it is deeper than its opening is wide, and a rock shelter is endogene.

Italy has the highest level of faunal biodiversity in Europe, with over 57,000 species recorded, representing more than a third of all European fauna. This is due to various factors. The Italian peninsula is in the center of the Mediterranean Sea, forming a corridor between central Europe and North Africa, and it has 8,000 km of coastline. Italy also receives species from the Balkans, Eurasia, and the Middle East. Italy's varied geological structure, including the Alps and the Apennines, Central Italian woodlands, and Southern Italian Garigue and Maquis shrubland, also contribute to high climate and habitat diversity.
