Lava from the 1855–56 Northeast Rift Zone eruption of Mauna Loa

Rubbly ‘a‘ā from the 1855–56 Northeast Rift Zone eruption of Mauna Loa dominates the foreground of this image, taken from a pull-off of the Saddle Road on June 26, 2022. This lava flow bypassed some vegetation, forming the forested kīpuka in the middle of the image. The slopes of Mauna Loa are visible in the background, amongst a cloudy sky. USGS photo by K. Mulliken.
