Mudpots are found at hydrothermal areas near the summit of Cerro Evermann. Fumaroles are active at the base of a relatively young lava dome, which is one of the youngest features of the summit area. The most active area is on the SE side of a northern dome and includes areas of emissions, boiling water or mud, clay alteration, and sulfur deposits.
