The photos were taken with 35MM black and white Kodak TRIX negative film. I along with nine others, took a flight from Hermosillo, Sonora to La Paz in Baja California Sur in México. I was at the University of La Paz where there were photographers, scientists, investigators, artists, TV and press media from all over the world. The year was 1991.
This experience was an in incredible natural phenomenon very different from 2017.
