摘要：	In 1988, ASCE began publishing a nationwide ground snow load map that requires local studies to be completed in areas where the varied terrain and complex weather patterns result in extreme variations in ground snow between the valleys, plains, and mountains. Several states in the Midwest and the Northeast regions have published region-specific descriptions of their ground snow loads. In 1964, approximately 11 states in the Western United States began publishing their individual reports that reflect local knowledge and case studies. Several states in the West (Western United States) have published two or more editions of their reports and maps. With the improvements over the past five decades in computing capabilities, database management, and cartography, the evolving and improved results of these studies can be observed. Idaho has produced three editions of their ground snow load reports, and the evolving process can be traced by perusing these three versions.
