2024 Map of Puupohakuloa

About this map

Honokua Lava Flow of 1950 and the Ka'apuna Lava Flow of 1950 define the geological character of this section of the Island of Hawai'i. The map documents the extensive reach of mid-20th-century volcanic activity as it coursed down the western slopes of Mauna Loa. To the south, the older 'Alika Lava Flow of 1919 overlaps the northern edge of Hawai'i Volcanoes National Park, showing the cumulative layering of the island's terrain over the decades.
