2017 Map of Umikoa

About this map

Mana Rd traverses the high slopes of the Island of Hawai'i, connecting the isolated settlements of Hanaipoe, Halepiula, and Umikoa. This 2017 survey documents a landscape dominated by dramatic volcanic topography and deep drainage channels, where numerous cinder cones or "pu'u" punctuate the ascending terrain. Notable landmarks include Pu'u'ula'ula, Pu'ukihe, and Iolehaehae at the higher elevations, while the lower reaches are carved by a dense network of gulches such as Hanaipoe Gulch, Waipunalu Gulch, and Kuikupapa Gulch. The arrangement of these small outposts along the mountain road suggests a history tied to high-elevation ranching or land management, far above the more densely populated coastal regions of the island. These traditional place names and topographical markers provide a clear view of the inland geography before modern development might alter these quiet upland reaches.
