The Extended Column Test (ECT) and the Propagation Saw Test (PST) are two commonly used tests to assess the likelihood of crack propagation in a snowpack. Guidelines suggest beams with lengths of around 1 m, yet little is known about how test length affects propagation. Thus, we performed 163 ECTs and PSTs 1.0–10.0 m long. On days with full crack propagation in 1.0–1.5 m tests, we then made videos of tests 2.0–10.0 m long. We inserted markers for particle tracking to measure collapse amplitude… CONTINUE READING
