The biggest clue to avalanches is ???... AVALANCHES! These slides, triggered remotely along a ridgeline, failed on the mid December drought layer.
It's game on, it's tricky out there, and the personality of our avalanche dragon is getting downright rowdy. In fact, slabs triggered from a distance are becoming the rule more than the exception.
Here's the setup... a strong cohesive slab rests on a Gong Show of weak, old, sugary snow, or in snow-geek-speak... a persistent weak layer (PWL) formed during the December dryspell. Whatever your classification, know that once triggered, any avalanche breaking into older snow will instantly ruin your day.
Here's what we do to keep it simple... it's time to pump the brakes and simply stay off of and out from under steep terrain.
