MR1, Moturakau rock shelter (Holocene of Cook Islands)

Where: Cook Islands (18.9° S, 159.7° W: paleocoordinates 18.9° S, 159.8° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Holocene (0.0 - 0.0 Ma)

• A total of 16 m2 of sediment, up to 1.8 m deep, has been excavated at Moturakau, revealing a stratified sequence of sandy layers that vary in organic content, weathered volcanic component, and density of cultural objects. The artifact assemblage features an excellent series of shell fishhooks (Allen 1991). The 1987 excavations at Moturakau Rockshelter yielded 14C dates on charcoal of 540 ± 70 yr B.P. from layer V, and 840 ± 80 yr B.P. from layer XIII, near the base of the shelter (Allen and Schubel 1990). Because the stratigraphy and chronology of the 1989 excavations at Moturakau do not correlate readily with those of 1987 (M. S. Allen, pers. comm.), I have not tabulated the bird bones from Moturakau stratigraphically.
