The summit lava lake in HalemaÊ»umaÊ»u Crater has dropped significantly over the past two days, as KÄ«lauea’s summit has deflated. The dropping lava level has allowed lava veneer on the walls of the Overlook crater to fall away, clearly exposing the contact between the original rim of the Overlook crater (which is the original, pre-overflow floor of HalemaÊ»umaÊ»u Crater) and the stack of recent lava overflows. These overflows are roughly 8 meters (26 feet) thick in total. Photo taken Tuesday, May 12, 2015 courtesy of USGS/HVO
