Title: Cooling and Avalanches: Date: 2012; Authors: Penelope H. Goddard; Description: Avalanches which occur during periods of cooling are important because they can surprise people, even very experienced practitioners. However, the inf...; Object ID: issw-2012-580-585.pdf; Keywords: freezing levels, slab failure, snow surface temperature, snowpack conditions; View additional details about Cooling and Avalanches

Title: Multiple Linear Regression Modeling and the Correlation Between Surface Area, Snow Density and Burial Depth of Improvised Snow Protection: Date: 2012; Authors: Salvatore G. Candela , Eeva Latosuo M.S.; Description: While there is a growing body of research on snow anchors, there has never been a published study on the use of improvised objects as snow protectio...; Object ID: issw-2012-650-656.pdf; Keywords: improvised protection, snow density, static forces, regression modeling, peak failure, snow anchors; View additional details about Multiple Linear Regression Modeling and the Correlation Between Surface Area, Snow Density and Burial Depth of Improvised Snow Protection
