1892 and 1894 cross-sections of Halemaʻumaʻu crater

1894 (approx.)

Detailed Description

Surveyor Frank Dodge's 1894 cross-section of Halema‘uma‘u overlaid on his 1892 cross-section. The 1892 lava lake was measured at 73 m (240 ft) below the rim of Halema‘uma‘u pit and by early-1894, the lava lake had filled the pit and frequently overflowed onto the caldera floor. The overlay of these two cross-sections shows a minimum elevation of the 1894 lava lake.
