2013 Map of Kahuku Ranch

About this map

Kahuku Ranch and the residential community of Discovery Harbour anchor this portion of the Island of Hawai'i, where the volcanic legacy of the 19th and early 20th centuries is etched into the landscape. The terrain is defined by several prominent volcanic events, including the Lava Flow of 1868, Lava Flow of 1887, and Lava Flow of 1907, which created numerous kipukas—islands of older land surrounded by younger flows—such as Kipuka Mamane and Kipuka Kapulehu. Cultural and ranching history are evident in features like the Heiau o Malino and the Rock Wall Corral. The map also traces the path of the Old Mamalahoa Hwy, illustrating the evolution of transportation along the southwestern slopes. Numerous puu (hills) and lua (craters or pits), including Puu o Kahuku and Lua Olai, dot the territory, reflecting the complex geological character of this region.
