The spring is also known as the résurgence de Chamouilley or siphon d'Ancerville. It was explored in 1987, 1994 and 2004–2005, when the way on beyond the restriction at 50 m was found.
- Depth and profile
- 855 m explored (2007 sheet; end at -2 m, lowest point -7 m); 1,180 m according to the GERSM. Restriction 50 m from the entrance.
- Configuration
- Restriction at 50 m, then a straight clay passage of ~700 m: sidemount. Backmount/CCR: tight at the restriction (estimate).
- DPV: DPV possible (estimate)
- The straight ~700 m passage would take a small scooter, but the restriction and clay-laden visibility limit the gain (estimate).
