Recent snowfall has formed fresh slabs 1 to 2 feet thick that sit over a weaker snow layer. You can easily trigger avalanches on most steep slopes.
In shallower snowpack areas, where the snowpack is less than about 4 feet deep, you can trigger a larger and even more dangerous avalanche that steps deeper into the snowpack. Low-angle slopes less than about 30 degrees without steep slopes above offer the safest riding options.
Also, avoid steep and rocky southerly slopes as snow heats up during the day.
