Aerial photograph shows the Ka‘apuna lava flow erupted from Mauna Loa in 1950 as it advanced through the forest at about 3,000 feet elevation on the morning of June 2. This rapidly moving ‘a‘ā lava flow traveled from the Southwest Rift Zone vent to the ocean in about 17 hours. Earlier flows from this same eruption reached the ocean in as little as three hours.

The Ka‘apuna flow traveled from the Southwest Rift Zone vent (7,800 ft elevation) to the coast in just 17 hours.

Beryl Spring is a hydrothermal area in some restrictive topography! The road from Norris Geyser Basin to Madison Junction follows the Gibbon River through a tight valley. With not much of a choice, the road threads between the river and Beryl Spring over some exceedingly hot ground.

A mounted topographic field party poses while working on the Dos Cabezas quadrangle in Arizona. 1940-1941. The quadrangle was surveyed by D.H. Rutledge, W.E. Burton, and G.K. Jensen, so it is likely that most or all of them are in this photo.
