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 Halemaʻumaʻu Crater) and the stack of recent lava overflows. These overflows are roughly 8 meters (26 feet) thick in total.
