"The six structures in Bruniquel cave are composed of speleothems or fragments of speleothems (speleofacts). The orange spots represent the heated zones, all located on the speleothems themselves. The red spot (structure B) represents a char concentration (mainly burnt bone fragments) on the ground. Map by Jacques Jaubert et al.
