This 1975 photo of the snow-covered summit of Mauna Loa from the SW shows the 2.4 x 4.8 km wide Moku‘āweoweo caldera in the center, with three circular craters in the foreground. South Pit (merging with the SW caldera rim), Lua Hohonu, and Hua Hou (foreground), formed through collapse along the upper SW rift zone. Mauna Kea is in the distance.
