About this map

Hanaipoe and 'Umikoa stand as focal points in this high-elevation landscape on the Island of Hawai'i. The terrain is defined by a dense network of drainage features, with Hanaipoe Gulch and Holuokawai Gulch cutting deep paths across the volcanic slopes. These gulches, including Kahaupu Gulch and Kaumō'ali Gulch, illustrate the complex erosion patterns characteristic of this region's windward-leaning geography.

Transport through this part of the island is concentrated along Mana Rd, which traverses the center of the map, and the Mauna Kea Ranch Rd in the northeast. Numerous named peaks and landmarks such as Pu'umali, Iolehaehae, and Pu'ukihe suggest a land use history tied to ranching and upland surveying. This 2013 survey provides a clear look at the persistent boundaries and natural features of the North Hilo and Hamakua districts.
