El Chichon (Chiapas, Mexico)

El Chichon volcan and the creter lake inside.

Volcano: El Chichon (see El Chichon at the Smithsonian Institution website in a new tab)
Type: Lake
Description: The El Chichón dome complex (1,100 m.a.s.l.) is located in the northwestern part of the State of Chiapas in southeastern Mexico. Currently, intense hydrothermal activity, consisting of fumaroles (mainly at the boiling point), steaming grounds, a soap-pool and an acidic (pH≈2.3) and warm lake (~30 °C) occur in the summit crater. With the low pH of the lake, CO2 is mainly present as a gaseous phase and dissolved in water.
