This study was undertaken to confirm the accuracy of the archive documents, to determine what areas the numerous unmapped cuts took place in, and to determine whether partialor clearcutting was the primary technique used. Stand parameters such as diameter distribution and species composition were used. Trees in each stand were also cored to determine age and to look for tree ring size releases caused by post-cut growth increases. Sugar maple dominated (shade-tolerant hardwood – TH), aspen dominated (shadeintolerant hardwood – IH) and mixed (MI) stands were studied. Age and diameter distribution indicated that all stands studied had been cut more recently than the 1920s and supported the claims of the archive documents. For the most part, the unknown-history stands were similar in average diameter and species composition to ...

In areas where nearby observational data is not available or where meteorological conditions change rapidly with distance, these typical data sources become less representative of the actual facility location, introducing substantial error.

Their support and encouragement have been more important than they can know. Finally, thanks to the many friends in the School of Meteorology and at St. Thomas More Catholic Church who helped keep me sane and entertained. v Table of Contents Acknowledgements .
