At the top of the cliff of the southern corner of the confluence, on an huge erratic block, two faces engraved :
- Panel 1 : is a very developped navigation scene, with 6 boats and half of another one (continuying into panel 2). Around them, 7 dogs, 1 elephant, 1 donkey, 2 ibexes and 1 bull. 3 men are on the boats, and 2 another around (including 3 bowmen and 2 men holding curved sticks). This scene can be dated from predynastic, but we can recognized at least two phases of engraving.
- Panel 2 : is another navigation scene, with 4 sickle boats and half another one (the second part of the boat beginning on panel 1). No human figure on the boat, but one unidentifiable animal and a man, both modern, below the upper boat. The boats at the right side of the scene are cutted by a modern vertical line.
