Recent strong winds have drifted fresh slabs of firm snow over the weak layer buried last weekend. Easterly-facing slopes with rounded pillows of firm snow will be the most hazardous. Although you are most likely to trigger an avalanche where winds have drifted snow, they will step down to buried weak layers two feet deep and possibly to the ground in shallow areas. You can trigger an avalanche from below and a distance; multiple people could ride a slope before you trigger an avalanche. You can find safer travel in areas sheltered from the wind with no slab or on slopes less than about 30 degrees.
