There's two main avalanche issues today... a persistent weak layer of snow buried in our snowpack and fresh pockets of wind drifted snow. I'll start off with the avalanche dragon that's most unpredictable and could instantly ruin my day... which is, the persistent weak layer now buried under yesterday's storm. Here's the setup-
Upper elevation slopes facing the north half of the compass are really the only game in town, but they're also the most dangerous because they harbor weak, shallow, old snow left over from early season storms. Life was good with our fragile snowpack until yesterday's storm rolled into town, delivering a one-two combo of snow and wind, which created a layer of strong snow on top of our weak snowpack. The problem with this structure is, it's gonna feel strong underneath us. However, we've gotta think not only about the snow we're traveling in, but also the snow we're traveling on and right now, we've got some junk in the trunk. Once triggered, even a small avalanche may break a bit deeper and wider than you might expect, failing on the mid portion of the pack, revealing obstacles hidden under the thin facade of our early season snowpack. Remember- any slide could easily result in a season ending injury if you get raked over stumps, rocks, or deadfall. So the best way to avoid unpredictable avalanche conditions is to avoid where it exists. We can still have a great day by playing in big open meadows and simply staying off of and out from under steep terrain facing the north half fo the compass.... easy :)
