2013 Map of Puuoo

About this map

The volcanic expanses of the Island of Hawai'i are documented here through a series of historic geological events. This high-altitude landscape is dominated by the intersecting paths of numerous eruptions, including the Lava Flow of 1843, Lava Flow of 1935, and the Lava Flow of 1881. These flows converge near the Humu'ula Saddle, a critical geographical corridor between the island's massive peaks. Evidence of human presence and infrastructure appears via the Mauna Kea Access Rd and Mauna Loa Access Rd, which facilitate movement through this austere environment. The Pu'u'o'o Ranch stands as a notable landmark of high-country land use, while various cinder cones and topographical features like Pu'uhuluhulu and Pu'unene define the surrounding horizon. The intricate drainage patterns of the Waikahalulu Gulch and Waiaama Gulch further illustrate the complex hydrology of the volcanic slopes.
