About this map

Mauna Loa dominates this high-altitude volcanic landscape, where centuries of geologic activity are recorded in overlapping basalt sheets. The terrain is a chronological record of eruptions, including the Lava Flow of 1843, the Lava Flow of 1935, and the Lava Flow of 1881, which together illustrate the shifting paths of magma descending from the Northeast Rift Zone. These flows cut across specialized conservation lands, including the Kipuka Ainahou Nene Sanctuary and the Mauna Loa Game Reserve.

Administrative boundaries converge here, marking the division between the North Hilo District and Kau District. The southern portion of the map transition into the Hawaii Volcanoes National Park and the Hawaii Volcanoes Wilderness. Significant cinder cones and vents such as Puuulaula and Puuwehi rise above the lava fields, while man-made additions like communication towers and a Cinder Pit signify modern human interaction with this active volcanic environment.
