A fumarole field is associated with the Salton Buttes. The field is characterized by gryphons and salses. These exhale carbon dioxide and steam, as well as ammonia and hydrogen sulfide. Some of these fumarolic vents reach heights of , and resemble the lava-erupting vents. Mud pots are also found. Parts of the field have recently emerged from the Salton Sea, due to dropping water levels, which have also caused the fumarolic vents to develop and grow noticeably, including an increased number of gryphons.
