From Hawaii News Now: After lava entered Green Lake, a 400-year-old freshwater basin in Kapoho Crater, around 10 a.m. Saturday, it created a massive steam plume that helicopters weren’t able to see through for hours. A Hawaii County Fire overflight at 3 p.m. reported that lava had filled the lake, apparently evaporating all of the water inside the basin.

Google Maps is going to have to do a lot up updating.
