1981 Map of Upper Piihonua

USGS Topo · Published 1982

About this map

Volcanic activity on the Island of Hawaii defines this high-elevation landscape, where successive historical eruptions have carved distinct paths through the native forests. Several major flows are recorded here, including the prominent Lava Flow of 1855 and the later Lava Flow of 1881, which intersect the dense woodlands of the Hilo Forest Reserve. These flows create a stark chronological record of the island's geothermal history, overriding the older terrain of the Upper Waikea Forest Reserve.
