1993 Map of Sulphur Cone

About this map

Sulphur Cone sits atop a landscape defined by the volcanic activity of Mauna Loa, where distinct volcanic events are preserved in the geological record. This survey delineates the massive extent of the Lava Flow of 1949, the Lava Flow of 1950, and the older Lava Flow of 1851 as they descend through the Southwest Rift Zone. The map captures the meeting point of high-altitude districts, showing the intersection of North Kona District and Kau District within the protected boundaries of Hawaii Volcanoes National Park and the Hawaii Volcanoes Wilderness. For the local historian or hiker, the presence of the Old Hawaiian Trail provides a trace of human passage through this desolate terrain of Kohalapilau and the land divisions of Keauhou 2 and Kahuku.
