About this map

Volcanic history dominates the central highlands of the Island of Hawai'i, where the high-altitude pass between Mauna Kea and Mauna Loa is clearly defined by the Humu'ula Saddle. This modern topography documents the successive layers of the island's formation, specifically mapping the extensive reach of the Lava Flow of 1843 and the Lava Flow of 1935. The presence of numerous cinder cones, such as Pu'u'ō'ō and Pu'uhuluhulu, illustrates the active geological processes that have shaped this terrain over centuries.

Transportation through this demanding environment is restricted to significant corridors like the Saddle Rd and the Mauna Kea Access Rd, which serve as modern lifelines through the high desert. To the west, the Pohakuloa Training Area represents a substantial federal footprint in the region, while drainage features like Waikahalulu Gulch and Waiaama Gulch incise the slopes, highlighting the erosional patterns of this alpine volcanic landscape.
