Macauley Island (2nd of 3)

Macauley Island

Macauley Island is composed mainly of black basaltic lava flows with a single, thick layer of white pumice and ash: the Sandy Bay Tephra. Radiocarbon dating of fragments of leaves and twigs from near the base of the tephra shows that it was ejected about 7,100 years ago.
