Snow and ice reports, 1936-1992

This subseries consists of reports and publications on the subject of snow and ice, including avalanches. Perhaps most significant here is the series of Borland's own reports on snow conditions causing avalanches in the ski areas and highways around Denver which present his data and observations, issued from 1952 through 1963. These and the other documents are indexed according to Borland's alphanumeric indexing scheme, which also dictates the arrangement.
