Abisso Ancona (Ancona Abyss) in The Frasassi Caves System

The Fracassi caves cover 8 geological levels and have an extension of about 30 km made of caves and narrow passages.

 

The beauty of this subterranean landscape comes from the huge stalactites and stalagmites that formed over the centuries.

Visitors have access to only 5 caves, which are spread over 1500 meters in length.

The first cave, which is one of the largest cave in the world, is called Abisso Ancona (Ancona Abyss). Estimating or sensing its magnitude is a main difficulty visitors may encounter. There are no “urban” points of reference, allowing for immediate calculation of its amplitude by a simple comparison. To help, we can only say that from the top of the cave ceiling, approximately in the centre, hangs a stalactite which is more than 2,50 meters long. But most people calculate its length as half a meter!

In the photo, a similar perspective misjudgement can be corrected by comparing the size of the people in the forefront with the beautiful stalactite structures in the middle of the photo.

PS. It was not easy getting a sharp photo of this scene. All of my photos, except this one, were severly blurred; unusable. If I remember correclty, I either pushed myself with the camera firmly against the wall behind me and pushed it againt my face, and then clicking, or I downright held the camera against the wall. I think I did the former alternative. Otherwise, the risk was big that the composition might have gone totally "Nort´South", even if the photo per se was sharp.
