Scope and Contents This is a summary of information gathered in a 1946 visit by Major Bekker to Germany to investigate soil and snow mechanics. The material has been recorded with reference to its relevance to Canadian snow conditions.

Scope and Contents The Avalanche Handbook was prepared for Forest Service officers concerned with the safety of skiers using winter sports areas within the national forests. At this time, the U. S. Forest Service was the only organization in the United States engaged in comprehensive avalanche research.

Scope and Contents A manual written as an update report for the research studies on avalanches completed by the U. S. Dept. of Agriculture, Forest Service in the publication, Avalanche Handbook, (1952).

Scope and Contents Information gathered during a visit to Swiss and Austrian avalanche research centers in August 1960.

Scope and Contents Observations made between 1933 and 1941 at an experimental station of the Kirov Railroad, Murmansk. The purpose of these observations was to investigate the conditions causing snow slides and explain the variation in slides due to the nature of their movements, the form of snow deposition, and the snow action on obstacles.

Scope and Contents State of Alaska, Department of Highways, Planning and Research Section in cooperation with U. S. Dept. of Commerce, Bureau of Public Roads. Research completed to determine the best means for reducing hazard and cost of avalanche damage to the existing Alaskan highway system, to determine appropriate control measures, and to assist locating engineers in selecting new routes in Alaska that minimize avalanche effects.

Scope and Contents An update on new techniques, equipment, and policies since 1961. Its publication was encouraged by the steady increase in snow safety problems accompanying the growth of the winter sports industry.

Scope and Contents A monograph containing a comprehensive review of the formation and occurrence of avalanches, together with a technical treatment of the principles and practice of avalanche defense. Major sections deal with avalanche hazard, snowfall, avalanche terrain, avalanche classification, stress and deformation in snow slopes, engineering mechanics, avalanche dynamics, avalanche defenses, design of supporting structures and galleries, avalanche triggering and slope stabilization, probability forecasting,...

Scope and Contents With the public's growing interest in winter sports, and skiing in particular, planning for efficient and safe facilities became the responsibility of the Forest Service.

Scope and Contents This folder contains publication on safe and efficient methods of on-loading people to the top of ski runs.
