A collection of reports about avalanche conditions and avalanche prevention measures on Washington mountain highways in general and to the North Cascade Highway in particular, involving various aspects of creep deformation and glide of the snow cover as they affect avalanche defense structure design; reconnaissance of a proposed new highway route through the Cascade Mountains: and a continuing study of the relationship between synoptic winter weather patterns and the formation and distribution of snow avalanches in the Cascades. The reports are entitled: 1) Effect of Glide and Creep on Rigid Obstacles by C.B. Brown and R.J. Evans. 2) Creep and the Snow-Earth Interface Condition in the Seasonal Alpine Snow-Pack by D.M. McClung. 3) In-Situ Investigations of the Temperature Dependence of the Creep of Low Density Snow by D.M. McClung. 4) Naches Tunnel Avalanche Reconnaissance by E.R. LaChapelle. 5) Investigation of Synoptic and Surface Weather Situations Leading to Major Avalanche Cycles in the Washington Cascades for the 1973-74 Winter by M. B. Moore. /FHWA/
