2013 Map of Kokoolau

About this map

Mauna Loa Observatory sits at the heart of this high-altitude landscape on the Island of Hawai‘i, reachable by the winding Mauna Loa Access Rd. The terrain is defined by volcanic activity across centuries, notably the massive Northeast Rift Zone and various volcanic vents like Dewey Cone and Steaming Cone. Geological history is recorded here through the extent of major eruptive events, including the Lava Flow of 1843, the Lava Flow of 1859, and more recent deposits from the twentieth century. The map provides a precise record of how these basaltic flows, such as the Ke‘āmuku Lava Flow and Ke A Po‘omuku Lava Flow, have shaped the island's high slopes, intersecting at landmarks like Pōhaku‘ohanalei and the crater of Lua Ioane.
