Paoha Island Most of Paoha Island consists of layers of lake sediments that were pushed up above the water level by rising magma (similar to the way in which the resurgent dome in Long Valley Caldera was pushed upward). But the north and east tips of the island consist of craters and lava flows that may have erupted as recently as A.D. 1720-1850. Paoha Island is a mere 230 years old. Hot springs and steam vents in the basin and around the lake show that it is still volcanicly active. The islands and the water within one mile of the islands are closed to public use from April through July to protect the bird nesting sites.
