1981 Map of Alika Cone

USGS Topo · Published 1981

About this map

Southwest Rift Zone dominates this volcanic landscape on the island of Hawaii, where the terrain is defined by successive volcanic events. The map provides a detailed record of recent activity, specifically the extensive Lava Flow of 1950 and the Alika Lava Flow of 1919, which cut across the high-elevation slopes of Kahuku. These flows illustrate the dynamic and evolving nature of the shield volcano's surface, preserving the paths of molten rock as they moved toward the coast. Notable geological landmarks include Alika Cone and the Umi Caverns, while isolated pockets of vegetation or older ground known as kipuka, such as Kipuka Nene, appear amidst the newer flows. A lone Trail winds through Ke A Pohina, suggesting the difficult passage through this active rift environment.
