Weak layers developing.

8th February 2018

It was a calm start to the day but there was little visibility above 700 metres. Due to the recent colder temperatures we have a deep seated weak layer developing within the snowpack. We also had a ‘whumphing’ sound on a steep slope, a classic red flag indicator of shear failure.

It can be tricky navigating through steep terrain in these conditions, some care required.

 

Using a probe, not only to work out snow depths but also it gives a good feel for layers within the snowpack.

 

At today’s pit site. Looking at a deep seated weakness within the snowpack. Fortunately the snow above this layer is well bonded.
