The aven des Grayets opens through an entrance 1.6 m by 2.6 m and continues through a succession of pits and meanders to a sumping low point at an elevation of -88 m.
Descrizione
Morfologia
The NNE-SSW-oriented entrance measures 1.6 m x 2.6 m. It continues into a 4.5-metre pit giving access to a 23-metre pit dug in steps. Another 23-metre pit, ending in a floor clogged with scree, follows.
By a 2-metre climb, one reaches a ledge from which a 6.5-metre pit starts. At its base, a chamber allows entry into the meander. Its route, 30 metres long, is interspersed with a 2.5-metre step and a 6-metre pit. The terminal pit is 15 metres. A meander branch with ledges joins perpendicularly another meander, which can be followed upward for 40 metres.
Idrologia
At the junction of the two meanders, a sumping low point provisionally ends the cave at an elevation of -88m[ref]Société spéléologique d'Avignon (SSA), "L'aven des Grayets": http://ssa84.e-monsite.com/pages/desobstruction/l-aven-des-grayets.html[/ref].
