The most recent volcanic activity at the Mount Edziza volcanic complex have been hot springs, several of which are found on the volcano's western flank, including Elwyn springs (36°C or 97°F), Taweh springs (46 °C or 115 °F), and inactive springs near Mess Lake. The springs are near the youngest lava fields of the Mount Edziza volcanic complex and are most likely associated with the most recent eruptive activity. These hot springs were highly important to the adjacent Tahltan people.
