- Summary:
- A now extinct volcano on the island of Hawaii, Lake Waiau is a shallow, heart-shaped body of fresh water that is located at 3969 meter elevation on the summit plateau of Mauna Kea. Geologic evidence indicates that this lake was likely formed during the Pleistocene when Mauna Kea was last glaciated and is probably the only site of the Central Pacific where a record of Pleistocene glaciation can be found. Sediment core from the lake bottom contains remnants of diatom populations spanning a period of more than 5000 years. As a result, the presence of diatom frustules, in conjunction with an analysis of the major chemical constituents of core and modern sediments, provided a unique opportunity during this study to assess changes that occurred with time in a highly isolated environment.
