Source de Landenouse
A walled resurgence pool on the north bank of the Lot about 1.75 km upstream of Cajarc, leading into a wide, shallow gallery that continues past 1,200 m to depths of about 90 m.
Landenouse rises in a masonry basin just below the D662, built long ago to hold water for two mills that no longer exist. In high water the basin overflows through a spillway; at low water its level can drop about 4 m because the spring no longer compensates for leaks.
From the bottom of the basin at about 3 m a vertical step leads to 6 m and a debris slope in a bedding plane descends to about 12 m, where a large horizontal gallery begins. The FFS fiche describes this gallery as 4 to 12 m wide and mostly 14 to 17 m deep, with a low point of 19 m, and calls it a large, clear sump that becomes slightly cloudy on the way out. The line was installed to 370 m at the time of the fiche.
Further in, earlier explorers reached 1,152 m at 60 m depth, and Jochen Hasenmayer reached 1,240 m and 90 m on 25 September 1980. The fiche also recalls that in 1970 two experienced cave divers died from bad air after surfacing beyond a sump in the nearby Cadrieu spring, about 1.5 km away.
환경
A broad bedding-plane gallery with a clay-sand and cobble floor, erosion scallops and dark manganese and iron deposits on the walls.
컨디션
The basin level depends on the season: it overflows in high water and drops about 4 m at low water.
