Plan traced from The Hidden River Project survey of Source de Landenouse (surveyed 2021-2024, drawn by T. Schnitter), whose GPS fix is the site position; north is rotated on the source sheet and has been turned back to north-up. The entrance is the walled pool at the foot of a ~7 m wall with a ladder; the single sump passage runs 2134 m to the current end at -33 after reaching -123 around 1400 m. Depths are the survey's water depths in metres, penetration labels are its p.xxx distances from the pool. The line is drawn on the passage centreline, so positions are approximate (within about 5 m); the owner's dives turned between 250 and 400 m, around the vertical zigzag ("screwdriver") near the 370 m bend.

Landenouse rises into the Lot about 2 km from Cajarc, below the D662. It belongs to no named system: it is a resurgence of the causse in its own right, and nobody has yet connected it to anything.

As of 2024 it has 2 134 m of surveyed passage and reaches 122 m deep. Nothing in this log goes anywhere near that — twelve dives here between 2019 and 2021, all in the 19–23 m band, which is the shallow entrance section.

The stored position is the GPS from the 2021–2024 survey.
