a fumarole. When surface water seeps down into porous rock layers it gets heated under pressure, and then as the superheated water rises back and nears the surface the pressure drops and it flashes into the steam of a geyser. Hot springs occur when water emerges that is not superheated or under pressure. Fumaroles do not have enough moisture to flow, so they vent steam. Mud pots form over fumaroles whose acid gases decompose rocks into mud and clay.
