1993 Map of Mauna Loa

USGS Topo · Published 1999

About this map

Mauna Loa dominates the landscape of this high-altitude survey, which documents the active volcanic morphology of the central caldera region. The map centers on the massive Moku'āweoweo caldera, detailing its complex floor with labels for the North Pit, South Pit, and specific eruption points like the 1940 Cone. These geological features are set within the vast protected boundaries of Hawaii Volcanoes National Park and the Hawaii Volcanoes Wilderness, where the terrain is shaped by successive events including the Lava Flow of 1949 and the Lava Flow of 1975. Evidence of human presence and access in this extreme environment is marked by the Mauna Loa Cabin and the historic Ainapo Trail, providing critical context for researchers studying the history of exploration and volcanic monitoring on the Big Island.
