This photo of Kīlauea's summit water lake was taken from the KWcam webcam site on the western caldera rim. The sharp color boundary between tan and dark brown zones is easily visible. A small greenish zone in the west end of the lake (bottom right of image) was more conspicuous today. These zones of greenish water correspond with areas of higher temperatures in the thermal imagery, and may represent zones of water influx into the lake. USGS photo by M. Patrick.
