At the moment Mexico City has volcanoes on several sides, particularly Popocateptl and Ixtaxcihuatl. In my youth I climbed to within about 400 feet of the top of Popo which was almost 17,800 feet at the time. It had snowed the night before and there was sheet ice near the top and I and people I was with did not have ropes. We did have ice axes and crampons. So we decided to turn around. There had been snow from 11,000 to the top and although we had put on sunscreen, a lot of us burned under our noses and chins and I had badly burned lips. The next day at college when we went to the nurse, she said, “Oh, you went to Popo. A lot of Acapulco people are coming in too, but they are burned on the top of the nose.”
