• Near the entrance, the floor of each cave was littered with hundreds of bones, as well as pieces of wood. The sediments from the different test pits are broadly similar to each other. They are very inorganic, being derived from basalts, with some secondary minerals (gypsum, flourite, apatite, minor calcite).

•Unit A: brown (7.5 YR 4/4 dry), reddish brown (5 YR 4/4 wet), moderately well laminated, poorly sorted, clayey, sandy, pebbly silt, alternating with well-laminated, poorly sorted, clayey, silty, sandy gravel; basaltic clasts very angular to sub-rounded; no reaction with 10% HCI; maximum observed thickness = 10 cm; indistinct lower contact (dashed line). Unit B: brown (7.5 YR 4/4 dry), reddish brown (5 YR 4/4 wet), unlaminated, moderately well sorted; silty, sandy, pebbly clay; basaltic clasts sub-angular; overall prismatic texture; strong reaction with 10% HCI; maximum observed thickness = 6 cm; sharp lower contact (solid line). Unit C\: Yellowish brown (10 YR 5/6 dry), dark brown (7.5 YR 4/6 wet), unlaminated, moderately well sorted, silty, sandy clay to clayey, sandy, gravely silt; basaltic clasts, rarely up to 20 cm in diameter, sub-angular to sub-rounded; strong reaction ith 10% HCI; maximum observed thickness = 22 cm; indistinct lower contact (dashed line). Unit Cy. light yellowish brown (10 YR 6/6 dry), dark brown (7.5 YR 4/6 wet), unlaminated, very poorly sorted, clayey, sandy, gravely silt; basaltic clasts rarely up to 20 cm in diameter, smaller clasts of flourite and calcite, very angular to sub-rounded; strong reaction with 10% HCI; maximum observed thickness = 6 cm; lower contact basaltic bedrock).)
