Émergence de la Dragonnière
A temporary spring in the Sagne valley about 1 km upstream of Cabrerets, near the Pech-Merle painted cave. The entrance lies at the end of a built tunnel under the D13, and the water level in the first 50 m varies with rainfall. A sandy squeeze at the bottom of a shaft was opened in 1991; beyond it short sumps (133 m at -12 m, then 53 m at -6 m) lead to multi-level dry passages, around 3 km in all.
Tiefe: 0–12 m
