Turnagain Pass Avalanche Forecast

Observations yesterday point toward weak snow at the ground in the upper elevations (above 3,000’) that show significant potential to propagate.  We are unclear how widespread these basal facets are across the forecast zone and with no other red flags (recent avalanches, whumphing or shooting cracks) reported in nearly a week, our snowpack is sending us a bit of a mixed message this weekend.  It’s the kind of avalanche problem (persistent slab) that may not present itself until a skier finds the sweet spot and triggers an avalanche, potentially after several tracks on the slope. So, if the plan is to push into bigger, steeper, above treeline terrain today, it’ll be worth digging a quick pit to see if you can find loose, faceted snow at the very bottom of the snowpack.  Look for snow with the consistency of a handful of sugar and if found, recognize that as your weak interface.

The snow quality right now is arguably the best it’s been in over a year so no doubt the usual zones in Turnagain will be crowded.  Keep other adjacent groups in mind as you are moving through the mountains today and maintain good backcountry etiquette.  Wear and know how to use your rescue gear, expose one person at a time on a slope, discuss potential consequences if a slope does slide and don’t ski on top of other parties.

8-10″ of new snow made for great skiing at 3,000′ on Sunburst ridge yesterday.  Keep in mind that If northerly winds kick up today earlier than expected, we’ll see shallow, sensitive wind slabs on slopes with a southerly tilt given the substantial amount of loose snow available for transport.
