Small cavity with an inclined forced conduit, a widening step, a low passage and a chamber with tubular chimneys, its lowest point sealed by dry clay.
Description
Morphology
A small entrance beneath a slab gives access to a short but pretty inclined forced conduit. It opens onto a step that widens. At the bottom, a low passage leads into a small chamber where tubular chimneys open, one of which joins the arrival step. The forced conduit at the start continues above the step and ends at a scree slope near the surface.
Hydrology
The lowest point is unfortunately irremediably sealed by very hard dry clay.
Bio
We observed in this cavity an enormous spider (10 cm).
