An aerial view from the south shows the North and South Inyo Craters phreatic explosion craters diagonally cutting forested Deer Mountain from the right center to lower right, and the unvegetated South Deadman lava dome and obsidian flow and the forested mound of North Deadman dome at the upper left.  Eruption of magmatic tephra and the formation of the phreatic explosion craters preceded emplacement of the lava domes and flows about 600 years ago.
