According to Szombathy's (1925) description of the locus `a' at Mladec I (Dome of the Dead), the human fossils were located directly below the surface calcite layer, and a similar position was reported by Smycka (1922) from another location of the same debris cone.
The karstic system of the Zlaty kun Hill resembles that at Mladec, being another multi-floor cave site, with skeletal remains of a female individual found in one of the deep cavities (the Prosek Hall) on the surface of a debris cone under a vertical chimney (Prosek 1952; Vlcek 1957; Kuzelka 1997; Svoboda 2000: figures 2-3).
