Aerial view of Halema‘uma‘u, showing typical spattering activity at the south lake margin. Golden brown Pele’s hair is covering the previous lake overflows which are darker in color. The plume was light at the time of the overflight, allowing a view of the southern wall, which recently experienced two collapses exposing the lighter wall rock beneath.
