Areas of combustion on the cave floor have been discovered throughout the whole of the cave. The original clay floors are only rarely preserved and many physical, biological and anthropogenic events may have led to these concentrations of charcoal. The area of combustion in the Candle Gallery is a structured hearth, composed of limestone plaques that do not exist in this area of the cave. Despite the small amount of charcoal present in this limited area of combustion, it has been possible to obtain a radiocarbon date of 30,000 years ago; in other words, in the Gravettian occupation phase.
