About this map

Mauna Kea dominates the southern landscape of this 2024 survey, with its high-elevation terrain carved by an intricate network of drainage channels. The slopes are marked by numerous cinder cones and volcanic peaks, such as Pu'ukea, Pu'u'ula'ula, and Pu'ukole. These natural landmarks sit above the ranching and forest lands where small settlements like Umikoa and Hanaipoe are established. Navigation through this high-country environment relies on the historic Mana Rd and the Mauna Kea Access Road Trl, which connect the remote outposts across the northern flank of the mountain.

Water management and erosion are evident in the steep-sided ravines, including Hanaipoe Gulch and Koholaiele Gulch, which drain toward the coast. The map illustrates a landscape shaped by both its volcanic origins and its contemporary use for land management and transit, with specific sites like Halepiula and Iolehaehae providing key reference points for those studying the geography of the Island of Hawai'i.
