The dive

A blue spring, according to the local paper the best-known in Haute-Marne. The water temperature is not published.

40–50 cm high flat passage at -19 m and squeezes in the entrance funnel: not for backmount or CCR.
Profile and sections

A blue spring, according to the local paper the best-known in Haute-Marne. The water temperature is not published.

It was first explored in 1967 and explored again in 1987: the end of the 700 m sump was reached on 1 November 1987, with side passages following in 1988–1989. Visibility was then very good.

Depth and profile
Sump 700 m: funnel to -5 m, max -19 m in a flat passage 40–50 cm high, roughly horizontal below -15 m. Beyond: ~1,100 m of dry passage with side sumps.
Configuration
Two squeezes in a boulder-choked funnel, a narrow 'canyon' and a 40–50 cm flat passage: sidemount with small kit only.
DPV: Not DPV-suitable (estimate)
Squeezes and a 40–50 cm flat passage: no scooter (estimate).

This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from public sources: plongeesout.ffspeleo.fr (FFS site sheets, mostly 1994–2007; Dhuit 2019), the GERSM and CDS 55, Wikipedia, grottomap (IKARE data), showcaves.com, Spéléo Club de Paris, ABIMES, the Maison lorraine de la spéléologie, the FFS, the Meuse département, JHM, Haute-Marne Attractivité, fontesdart.org, MedSubHyp and CDS 07 (September 2026). Much of the dive data is old or comes from a single exploration team. Pins from Wikipedia and grottomap or converted from plongeesout's Lambert coordinates; the Dhuit has no pin yet. ~ = estimate.
