A view of the active lava lake within Halema‘uma‘u, taken during a Kīlauea summit monitoring field shift on the morning of May 18, 2022. The active lake is draining into the small pond on the right of the photograph. Spattering along the margins of the lake is common, seen here in the center of the photograph.
