During the decades of their excavations, the archeological investigators carefully followed the shelter's natural and human-made layers, recovering thousands of chipped-stone tools, animal bones, shell, charcoal, and other traces of the past. They identified and mapped 27 layers, or strata, revealing a record of human occupation from Paleoindian through historic times.

Another view of the cliff behind which lies Chauvet Cave. The present entrance and the original or Paleo entrance are shown in red and blue respectively. The original entrance was closed, covered in scree which fell from the cliff above, more than 20 000 years ago.

We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta's pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications. The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery.
