About this map

Mauna Loa dominates this landscape, its summit crowned by the vast Mokuaweoweo Crater within the northern reaches of Hawaii National Park. This 1920s survey documents the active volcanic history of the region, specifically delineating the paths of the Lava Flow of 1851, the Alika Lava Flow of 1919, and the recent Lava Flow of 1926.

The map reveals a high-altitude wilderness marked by specialized features like Umi Caverns, Sleeping Cave, and several essential waterholes such as Lua Poholo. Human presence is traced through an Ancient Trail and the Menzies Trail, alongside infrastructure like the Noguchi Tunnels and Clark Tunnel near the Kau Forest Reserve boundary. The detailed topography illustrates the raw geological evolution of the North Kona District and Kau District.
