Perched lava pond between Mauna Ulu and Pu'u Huluhulu, Jan 25, 1975

Perched lava pond forming between Mauna Ulu and Pu'u Huluhulu, January 25, 1974. Several episodes of renewed growth in height of Mauna Ulu occurred in early 1974. The first sent much lava toward Pu'u Huluhulu, where a perched lava pond developed. This photo shows lava in the pond spilling over the enclosing levee and making it higher. Visitors to the summit of Mauna Ulu today walk across the flat surface of this perched pond.
