2013 Map of Ahumoa

About this map

The high-elevation saddle between massive volcanic peaks on the Island of Hawai'i is dominated by the military infrastructure of Bradshaw Army Airfield and the nearby Pʼnhakuloa Camp. This 2013 survey illustrates the stark, high-altitude landscape where ancient cinder cones, or pu'u, such as Ahumoa and Pu'upʼnhakuloa, dot a terrain marked by the Ke'āmuku Lava Flow. The transportation network is anchored by the Mauna Kea Loop road, providing access to this demanding environment. Water remains a critical and scarce resource in this region, evidenced by the presence of isolated points like Hopukani Springs, Waihi Spring, and Liloe Spring. The map documents a complex geography of drainage gulches, including Kemole Gulch and Pʼnhakuloa Gulch, which carve through the volcanic slopes of the island's interior.
