2024 Map of Piihonua

About this map

Island of Hawai‘i volcanic history is etched into the landscape here, where several distinct volcanic events have shaped the topography above Hilo. Major events including the Lava Flow of 1855, Lava Flow of 1881, and Lava Flow of 1852 are documented as they descend toward the coast, with the Lava Flow of 1942 marking a more recent addition to the geological record. The Wailuku River cuts through these basaltic layers, creating a series of dramatic water features such as Boiling Pots and Peepee Falls.
