Abstract
Frost observations during the winter and spring of 1949-1950 indicated that pronounced soil freezing conditions existed in the ponderosa pine, lodgepole pine, grass and brush types in eastern Oregon and Washington. Accordingly, a study was designed to determine the occurrence and character of frost under these widespread forest and range types. This paper presents a progress report of observations on soil freezing conditions in these cover types in eastern Oregon during the winter and spring of 1950-1951.
