The PST


Propagation Saw Test - the latest of the large column tests (ECT, PST) used as follow up evaluations to the standard compression test. The compression test does a great job in identifying weak layers and suggesting if they are likely to initiate a failure within the snowpack. The limit to the compression test is its inability to indicate whether the failure is likely to propagate into an avalanche.


To continue I've summarized the PST, including cited images and diagrams. Also includes a video of the test being conducted
