For many years there has been much interest in moisture studies of forest fuels. The study reported here was in its 17th year when the author became involved. The study was terminated 2 years later. All data were compiled, adjusted, and analyzed; a report was prepared but not published. Continued interest in moisture content of large fuels prompted the author to reexamine the data, computerize the equations, and rerun the prediction curves along with the addition of a very dry year (1967) and a moderately dry year (1972). The results indicate major differences in large fuel moisture by exposure and season. Unusual years stand out from the average. The equations are useful but should be applied with discretion.
