A report of an analysis of snow survey data from 163 snow courses in the Central Sierra Nevada in California is presented. The analysis uses factor analysis and principal component regression analysis and includes recommendations for the location of snow survey courses that will better fit the terrain and produce better analysis of runoff. Definitions of 37 variables considered in the analysis are tabulated with symbols, means and standard deviations. Snow water equivalent for March 1, April 1, and May 1, for the years of 1958, 1959, and 1960 were used as dependent variables. The principal components of analysis were made to answer two questions, (1) what is the relation of snow to simple terrain variables, with respect to different years; (2) what factors contribute most towards explaining differences in snow between snow courses. The text describes electronic computer readout tables and graphical representation of data relationship, also factors related to the best probable location of snow survey courses.
