Title: The PST with a Twist: Comparing the Standard PST to the Cross Slope PST: Date: 2014-09-29; Authors: Eric Knoff; Description: In recent years, the propagation saw test (PST) gained popularity for both avalanche professionals and backcountry recreationalists. A limiting factor...; Object ID: ISSW14_paper_P2.30.pdf; Keywords: propagation saw test (pst), cross-slope propagation saw test (cpst), extended columntest (ect), critical cut length, slope-angle, fracture propagation; View additional details about The PST with a Twist: Comparing the Standard PST to the Cross Slope PST

Title: Uncut Column Stability Tests For Hard Slab Snow Conditions: Date: 2013-10-07; Authors: Wesley R. Farnsworth, Markus Eckerstorfer; Description: This study aims to better understand a slabs influence on the mechanics of artificial avalanches. It seems that stability tests do not represent stab...; Object ID: ISSW13_paper_O2-01.pdf; Keywords: slab properties, propagation saw test, hard slab, uncut columns; View additional details about Uncut Column Stability Tests For Hard Slab Snow Conditions

Title: Edge Effects In Propagation Tests: Date: 2013-10-07; Authors: Edward H. Bair, Ron Simenhois, Alec van Herwijnen, Karl Birkeland; Description: Guidelines suggest beams with lengths around 1 m for Extended Column Tests (ECTs) and Propagation Saw Tests (PSTs). The longest unstable tests publish...; Object ID: ISSW13_paper_O5-02.pdf; Keywords: crack propagation, extended column test, propagation saw test; View additional details about Edge Effects In Propagation Tests

Title: Using High-Speed Video to Better Understand Extended Column Tests: Date: 2012; Authors: Karl W. Birkeland, Alec van Herwijnen; Description: Extended Column Tests (ECTs) have become increasingly popular for assessing snowpack stability. However, we still do not fully understand what happen...; Object ID: issw-2012-098-103.pdf; Keywords: extended column test, propagation saw test, snowpack stability test,; View additional details about Using High-Speed Video to Better Understand Extended Column Tests

Title: Deformation Analysis of the Propagation Saw Test: Date: 2010; Authors: Chris Borstad, David McClung; Description: We present results of high speed photography films which show that the scale of slope normal deformation prior to unstable fracture in the propagatio...; Object ID: ISSW_O-009.pdf; Keywords: propagation saw test, kootenay pass, british columbia; View additional details about Deformation Analysis of the Propagation Saw Test

Title: The Effect of Additional Snow Load on Extended Column Test and Propagation Saw Test Results: Date: 2010; Authors: Ron Simenhois, Karl Birkeland; Description: The number of skier triggered dry slab avalanches typically increases during or shortly after snow loading events. However, field observations and res...; Object ID: ISSW_O-041.pdf; Keywords: extended column test, propagation saw test, snow, dry slab; View additional details about The Effect of Additional Snow Load on Extended Column Test and Propagation Saw Test Results
