Extreme ice thicknesses from freezing rain
Final Report
Appendix. Maps for mean recurrence intervals of 50, 100, 200, and 400
years
Maps with English units (ice thicknesses in inches, wind speeds in miles per hour) are in
Appendix A. Maps with metric units (ice thicknesses in millimeters, wind speeds in meters per
second) are in Appendix B. For each mean recurrence interval, the map of the 48 contiguous
states is followed by the Alaska map and then the three detail maps for Lake Superior, the
Columbia River Gorge, and the Fraser Valley. The maps are arranged in order of increasing
mean recurrence interval.
