With my ALMA host, William Garnier, who flew from Santiago to the far north of Chile to accompany me to the 5,000 meter high site, after passing a mandatory medical exam for the ascent. This is where the oxygen became so thin that our car and electronic equipment had trouble working...hence the oxygen tube in my nose. The ALMA antennas are in the background. November 2011.
