The torch smudge marks are there.

On the walls of the passages that lead to this location, the carbon deposited by ancient flames is still visible to those who know what they are looking at.

The marks are not dramatic — they are not paintings or carvings or symbols.

They are simply the darkening of the rock surface where combustion products contacted the stone.

But they are there.

They have been there since the man passed through with his torch, approximately 8,800 years ago.
