Quick video on how and why I dig a snowpit and my two favorite stability tests for once my test pit is dug. A test pit ID's snow layers, grain types, and performs stability tests. Whereas a study pit collects all of that information plus temperature.
WHY: I only dig a pit when I am in a new to me snowpack or there are weak layers of concern buried in the snowpack, like buried surface hoar, facets, or a rain crust I want more information about. I am specifically targeting those weak layers to gather data about its reactivity, sensitivity, and likelihood of propogation.
My Compression Test (CT) helps me ID layers & fracture characteristics and my Extended Column Test (ECT) helps me determine that layer's likelihood of propogation.
