Mount Griggs is the prominent stratovolcano at the upper left in this aerial view from the SW. The slopes of the volcano are heavily mantled with ash from the 1912 eruption of Novarupta volcano. The 1912 pyroclastic-fall deposits also mantle the irregular surface of Knife Creek Glacier, which flows from right to left behind the ridge in the lower right foreground.
