Pit tests and skier triggering

Postby danshorb » Wed Feb 24, 2016 2:27 pm

Here's another interesting video about pit results vs. actual skier triggering. One statement made is that skier triggering that occurred along side CT24-30 may mean that the CT24-30 may be a false stability, or can point toward individual pit accuracy across a slope.

Bruce Jamison's well-made point is that shear quality matters at least as much as the amount of force needed to cause the fracture. Considering both will give you a more accurate understanding of your compression test results. Keep in mind that the compression test is not always the pertinent test...a topic covered by BJ in other articles. Refer to pg 4-5 of your AIARE Field Book for a reference of when specific tests are relevant.
Will you have false negative CT test results...sure, as with most any test. That's why choosing terrain wisely and travel techniques are necessary to improve your safety.
