The area is very active geologically. There is a geothermal plant here, and an area that reminds us of Yellowstone. This lake smells strongly of sulphur, and when the light is right is a bright green.
Here we are at Dieng's version of Yellowstone. The hawkers here are selling tiny potatoes, some as small as grapes. We bought some. They were tasty boiled with butter and parsley.
