1956 Map of Puu Koli

About this map

Keamuku Lava Flow and several historic volcanic events define the geological character of this high-elevation landscape on the Island of Hawaii. The sheet provides a clear visualization of the Lava Flow of 1843 and the more recent Lava Flow of 1935 as they descend through the Mauna Kea Forest Reserve. This mid-century survey captures the rugged interior where the Kaohe Game Reserve meets the volcanic slopes, centered around the Humuula Saddle. Civil infrastructure is represented by the Saddle Road and the Hilo Kona Road, which provided vital transit across the island's interior. Small outposts and surveying points like Manus, Puuahi, and the summit of Puu Koli are documented, along with natural features including Lava Tubes and a prominent Crack, illustrating the raw volcanic terrain before further modern development.
