1963-64 I finished a three year degree with a physics major at Melbourne University in 1963. I built a portable Geiger counter for a physics project. I did my first geophysical prospecting with this instrument. Not being excited by available prospects in physics, I did an extra year of undergraduate studies during which I completed majors in geophysics and mathematics plus a first year geology course. Four days after I received my final exam results, BHP sent me to lead a seismic refraction crew in a peat bog in northeast Tasmania. My experiences on this survey, where I was a danger to myself, the crew, and the environment, have been described in Preview previously (Gunn, 2012).
