Yesterdays close call is a firm reminder that it is still winter in the high-country, and although the chances of triggering a big slide as a rider are going down but it is still possible. If you do trigger it, the consequences remain the same today as they were last week when we had high.
This past weeks storm was not enough to wake up our PWL in a widespread fashion, but a few recent avalanches have queued us in to where we are currently at with the snowpack structure and hazard. On northwest through east facing slopes, recent avalanche activity and tests suggest the likelihood of triggering this avalanche problem is going down and mid-elevations are nearly there -- This is good news. On the flip side, we are not out of the woods yet and poor structure exists in many upper elevation areas where a dense slab still sits atop stubborn, weak and sugary faceted snow from the January dry spell.
It's tricky because we can trench multiple sets of tracks on a slope without incident, but all we need to do is find a weakness where the slab and weak layer are susceptible to our weight, maybe around a rock or a bush, collapse the pack, and now we have triggered an avalanche big enough to ruin our day. With that in mind, I am still avoiding suspect areas where this avalanche dragon lives. Steep, rocky, shallow slopes on the north half of the compass that are complex and have a lot going on are still off the table -- I can not outsmart this problem, so avoidance is my go-to tool for this dragon.
