Topographic map of Fontéchevade. The V-shaped contour in the middle of the map is the cave entrance.
Two profiles through the cave and the plateau. The top profile is at the dripline. The bottom profile is near the back of the cave.
A south-north profile of the cave. The figure is standing at the dripline. The rise in the floor to the right of the figure is the profile as left by Henri-Martin. The fill almost reaches the roof of the cave at the far right. Just beyond this point there is a filled chimney.
Electroresistivity was used to map the bedrock over and around the cave. The lines that crossed over the back of the cave helped confirm the presense of a chimney.
