Andy and Bo noted.... "recent wind drifted snow sitting on top of the old, faceted snow surface. This was where we noticed todays avalanches failing on ridges and exposed ridgelines. Easy to manage, and even easier to avoid!"
Winds are gonna help change the landscape and add a little spice to steep drifted slopes around the compass. Don't forget, fresh drifts will form on a variety of snow surfaces, including faceted snow, and today's wind slabs are gonna be big enough to pack a punch, letting me know who the boss really is. So, I remind myself... even a small slide in consequential terrain could ruin my winter season if it strains me through rocks, cliffs, or trees.
Fortunately, we can steer clear of this problem today... lose the wind and you lose the problem. Simply lose some elevation and hone in on wind sheltered terrain. In addition, look for and avoid fat, rounded pillows of snow on the leeward side of ridges, gully's, and cut banks, particularly if they look textured or sound hollow like a drum. And finally, stomp around on small test slopes like road cuts similar to what you wanna ride and see how they're reacting before pulling the trigger on a big slope.
Above is an example of a leeward slope that has been previously wind loaded and has all the right visual warning signs to observe.
