Updated 20th November 2022

The information below has been roughly translated from the French, Spéléo-Club Dijon reference, Simonnot G, 2022.

   A sink pitch develops in length over ten metres, 8 m deep at one end and only 4 m at the other. Two metres in height, a severe skylight has been enlarged using straws and drops into the middle of a parallel shaft. The bottom of the vertical is unfortunately completely filled with sandstone blocks (hopper on the entire side of the pitch). The particularly noticeable strong suction air current at the window must escape through the chaos.
    The very important sink receives the outflow from the Fuente de Meses (MCP5308 / SCD3445) just above. It opens at the top of the Vallina limestone formation. The small entrance shaft was probably explored by Spanish speleologists (EC Tortosa or AEC Lobetum?). It was seen again on June 9, 2018 by the Dijon Speleo-Club. The window allowing access to the second pitch was opened on September 2, 2022 by David Gonzalez Cobo, Guy Simonnot and Magin Ulises.
