On Saturday, September 30, 1967, I went to the Port Authority Building on 41st Street and 8th Avenue. I bought a copy of the New York Times and a Signet paperback called Earthworks by Brian W. Aldiss. Next I went to ticket booth 21 and purchased a one-way ticket to Passaic. After that I went up to the upper bus level (platform 173) and boarded the number 30 bus of the Inter-City Transportation Co.

My concern with salt lakes began with my work in 1968 on the Mono Lake Site-Nonsite in California. Later I read a book called Vanishing Trails of Atacama by William Rudolph which described salt lakes (salars) in Bolivia in all stages of desiccation and filled with micro bacteria that give the water surface a red color. The pink flamingos that live around the salars match the color of the water. In The Useless Land, John Aarons and Claudio Vita-Finzi describe Laguna Colorada: “The basalt (at the shores) is black, the volcanos purple, and their exposed interiors yellow and red. The beach is grey and the lake pink, topped with the icing of iceberg-like masses of salts.” Because of the remoteness of Bolivia and because Mono Lake lacked a reddish color, I decided to investigate the Great Salt Lake in Utah.
