Kelimutu, Indonesia
The volcano contains three striking summit crater lakes of varying colors. The lake colors vary on a periodic basis. Sub aqueous fumaroles are the probable cause of active upwelling that occurs at the two eastern lakes. The visitor is never quite sure what color the lakes will be when they reach the top.

Xico, Mexico
Xico volcano sits at the extreme southern end of the Mexico City. For a geologically significant chunk of time, this area was underwater, drowned by Lake Chalco. The lake began to dry out in the 1300s, and Aztec fishermen settled along its coastline hereabouts. In the nineteenth century, the government drained the lake entirely.
