(A) The anomaly due to a possible body (green) is clearly below the roof. The depth is owing to a velocity of 0.10 m/ns of the above rough geological layer and is valid to a depth of 2 m. (B) The corresponding depth-slice in which the geometry of the cave (circled) and, in green/yellow, the same anomaly detected by the radargram are clear. The cave entrance was not covered by the ground penetrating radar (GPR) investigation.
