When explored in March 2017, it turned out to be a 7m shaft to a chamber.
The information below has been roughly translated from the French, Spéléo-Club Dijon reference, Simonnot G, 2018.
On a limestone shelf, this pretty, 4m diameter pitch, is surrounded by barbed wire. Pitch of 7 m, the spacious bottom (4.5 x 2.5 m) on a slight slope (-8) is impenetrable (large blocks of collapse, no draft). Three meters above the bottom an inclined bearing marks the arrival of a high entrance (+2)
Trillos limestones (base of level b).
