File contains 10 transparencies of clouds. Each transparency, except 1 that has "AZ.56" (and also labelled "Nicola Lake"), has the code "MZ" and a number that ranges between 251-272. File also contains the article "What the Clouds Mean" by Don Kent that was formally stapled together and also has "Horticulture March 1973" written on the first page along with markings that indicate Fenner's photographs that were used. Contents were originally in folder labelled "Clouds", and transparencies were in an Agfa roll film package that had Fenner's address ("Clifford A. Fenner | 1674 Peters Road | North Vancouver, B.C.") within the folder.
