About this map

The high-elevation volcanic slopes of the Island of Hawai'i dominate this 2017 survey, characterized by a complex network of cinder cones and drainage features. The landscape is defined by the massive Ke'amuku Lava Flow in the southwest and the rising elevations of Mauna Kea's western flank. Strategic infrastructure is represented by Bradshaw Army Airfield near the southern boundary, situated alongside Saddle Rd.

Numerous prominent pu'u, or hills, such as Ahumoa, Pu'ula'au, and Pu'upohakuloa, serve as critical landmarks across the arid terrain. The map records vital water sources in this dry environment, including Hopukani Springs, Waihu Spring, and Liloe Spring, which feed into deep incisions like Pohakuloa Gulch. Historic paths and modern access routes including the Lightning Trl, Malahini Rd, and Menehune Rd cut across the volcanic soils, tracing the connectivity of this unique upland region.
