The following deep-zoom version of an adaptation of part of the main plan survey of the system published in Scialet 38 shows how the cave fits into the system.
The following cross section drawn by Gilbert Bohec also helps to clarify where it fits into the system.
Red passages indicate the Vouay - Chevalier route; blue passages the Vouay - Trou du Glaz route
