Mark's time lapse of the big dig near Iron Mountain Friday... it's becoming a major chore just to excavate a snowpit and locate the November facets (PWL)
It's increasingly clear... there's a light at the end of the Persistent Weak Layer tunnel. So, you're wondering... is it open season? Man, I think we are getting so close and the recent series of storms is a huge test. While the snowpack appears Herculean and for the most part unreactive, as I begin stepping into big terrain I know it's not entirely impossible the trigger a deep slide. All I need to do is find one weakness in the pack, pull the rug out from underneath, and the entire roof crashes down on me. Likely suspects include steep, rocky terrain or slopes that avalanched earlier this season that have remained thin and slightly weaker. It's a low probability/high consequence scenario. And unless you've got avalanche goggles and can peer into the layers of the snowpack from a distance, now is the time to continue stepping out cautiously, but with intent, gathering as much snowpack intel as we can along the way.
