Original caption: "On Wednesday evening (September 7), the lava lake at Kīlauea's summit reached a high level, about 8 m (26 feet) below the floor of Halema‘uma‘u Crater. This panorama shows the former Halema‘uma‘u Overlook (closed since 2008 due to volcanic hazards) at the far left. Jaggar Museum, visible on the skyline in the upper right part of the photo, is a popular destination in Hawai‘i Volcanoes National Park for viewing the lava lake activity and spattering lake surface."

Hawai‘i's Highest and Lowest Elevations

Highest Elevation: Mauna Kea
Mauna Kea, a dormant shield volcano on the island of Hawai‘i, is the state’s highest point at 4207 meters (13,803 feet) above sea level. A product of hot spot volcanism, much of this volcano’s bulk is below sea level—when measured from the ocean floor, its total height is actually 10,100 meters (33,100 feet).
Lowest Elevation: Coastline
The lowest points in Hawai‘i are found at sea level along its coastlines, where the shoreline meets the Pacific Ocean.
