A helicopter overflight provided aerial photographs of Kīlauea caldera on May 29, and these photos were used to construct a 3D model. The water lake is visible as the tan area in the deepest portion of Halema‘uma‘u crater. For scale, the water lake is 270 m (885 ft) long and approximately 600 m (1970 ft) below the western caldera rim. USGS photos by K. Mulliken.
