Figure 4A. Tree-kill area near the base of the south face of Mammoth Mountain. A high percentage of the trees in the foreground are dead due to high CO 2 concentration in the root zone of the soil. Trees higher on the mountain are unaffected. (Looking north from the northwest shore of Horseshoe Lake.)
