1981 Map of Mauna Loa

USGS Topo · Published 1981

About this map

Mokuaweoweo caldera dominates this high-altitude survey of the Mauna Loa summit, where geologic activity is documented through a series of dated volcanic events. The landscape is defined by the Southwest Rift Zone and significant depressions including North Pit, South Pit, and Lua Poholo. For those researching high-mountain history, the map identifies the Mauna Loa Cabin and the secluded Jaggars Cave (Shelter), providing a record of human presence amidst the lava fields. The document tracks the expansion of the mountain's surface over several decades, specifically labeling the Lava Flow Of 1949, the Lava Flow Of 1975, and the Lava Flow Of 1926. These labeled flows illustrate the progressive reshaping of the Hawaii Volcanoes National Park and neighboring lands such as the Kapapala Forest Reserve and the Mauna Loa Forest and Game Reserve.
