Snowpack Discussion

Avalanche danger remains Considerable (3) above 3000 meters.  Snowpack observations yesterday revealed the weak layers within the new storm snow to be bonding.  Wind slabs appear to be bonding and losing their reactivity as well.  We found 3mm depth hoar on the ground at 3700m on North facing aspects that failed repeatedly upon isolation with extended column and compression tests.  What this means is we currently have a persistent slab problem, with our new snowfall of ~100cms (due to settlement) sitting on top of a persistent weak layer on the ground in the Alpine (above 3000m).  If history proves correct, the depth hoar is located not only on North aspects, but also all other aspects above 3000 meters. It’s essentially located anywhere there was early season snow on the mountain.  A skier once described it as “a mattress sitting on top of ball bearings”, which is an apt visualization of our current avalanche problem.  For this reason alone the avalanche danger remains Considerable (3) in the Alpine. If you choose to ski the Gulmarg backcountry, you can avoid this avalanche problem, by staying on ridgelines, keeping your slope angles low, and avoiding large unsupported slopes.  We will be going out for more snowpack tests today. Tracks on a slope do not indicate that it is safe. A good mindset for the current avalanche conditions is, “Am I getting away with this, or am I choosing terrain appropriate for the current avalanche conditions.”

Choose to ride in groups in the forests of Gulmarg. http://www.deepsnowsafety.org/index.php/. We now have enough snow in the conifer forests above 3200 meters for skiers and riders to get trapped in tree wells. Read more about this phenomenon in the link above. It causes several fatalities each year in other ski regions of the globe.

Avalanche Problem #1 – Persistent Slab

Release of a cohesive layer of soft to hard snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
The best ways to manage the risk from Persistent Slabs is to make conservative terrain choices. They can be triggered by light loads and weeks after the last storm. The slabs often propagate in surprising and unpredictable ways. This makes this problem difficult to predict and manage and requires a wide safety buffer to handle the uncertainty.
