Plan traced from the 1994 survey by Francis Menu (B.R.E.N. / CDS 27) reproduced on plongeesout, a small low-resolution sketch: the scale bar is illegible, so the scale was set from the survey's own 100 m and 300 m distance marks (about ±15%), and its north arrow (pointing left on the sheet) was used for orientation. The entrance lies at -11 m in the bed of the Lot below the Saut de la Mounine; the passage stays around -7 to -10 m for 200 m, drops through a chamber (-23) with a short side passage, reaches -47 and ends at 360 m (-41) on breakdown and small impassable leads. The river bank line is the one drawn on the sketch; depths and distances are the survey's labels and all positions are approximate.

Also called Ressel 2, which sets expectations it does not entirely meet. It is an independent siphon in the left bank of the Lot just below the Saut de la Mounine, with no named system behind it.

The name is a person. M. Cunhac showed the source to the cave divers who explored it in 1994, and it has carried his name since.

Five dives. The position used to be Impasse de Cunhac — a driveway 64 km east, matched on name alone.
