Adams Glacier descends from the summit of Mount Adams, seen here above Takhlakh Lake on the NW side. The main edifice was constructed primarily of lava flows during the Pleistocene, but flank vents produced lava flows and explosive eruptions during the Holocene. The Takh Takh Meadow lava flow originated from a vent low on the NW flank and traveled a total of 10 km, reaching several kilometers beyond the east (left) side of Takhlakh Lake.
